2nd Degree Trinomial Rules

Solve by factoring

a x c = # II a + c = b

Do t-chart. Refer to Algebra 1 stuff if needed

If the factoring isn’t working, do this…

1. Standard form (everything on one side of equal side = 0)

2. Factor out greatest common denominator

3. Ignore original equation and proceed with t-table

4. Once you get the factors, add them in as “gx” and “fx” into the “abx” area

ax^2 + bx +c

ax^2 + gx +fx + c

5. Split into 2 parts and find gcf then for use the common gcf as the other thing to multiply

(a+b)(a+b) or whatever

180 days till exams

Hey everyone. As it is officially the 1st of November its time for Christmas. I'm gonna cry if sm says its too early.

Finished the book of John and now on Mark 2

Completed some trinomial factorisation work today

Started working on the 2nd draft of my debut novel

Finished working on my scratch game for a completion check it out btw.

Finished a history practice test today, and I will get the results on Monday so in general today was very productive.

180days til exams 😭

i am the exact opposite of people who need someone to sit in their room while they do work. i cannot do my schoolwork during free time in class because there are too many people around me

Apropos of nothing, I'm reminded of a toy I had as a child: the Montessori Trinomial Cube.

It's about six inches a side, split into segments of 1, 2 and 3, forming 3 sub-cubes and 24 prisms. The square sides of all blocks are colored, the others are black. (A smaller Binomial Cube also exists.)

I liked it and learned to speed-assemble it blindfolded. A teacher who knew me commented that practicing with it was part of why I was so good at maths later in life. In retrospect, I think that's an example of statistical confounding: The cube was not causative, I was good with the cube and good at maths for a shared reason.

how do you factor trinomials.

Early Childhood - Trinomial Cube

Look at that focus! The binomial cube, when first introduced to the child, is presented as a challenging, three-dimensional puzzle. The cube is made up of a number of colored blocks, which fit together in a specific way. Assembling it uses a child's fine-motor skills and requires the ability to discriminate between the blocks based on multiple characteristics. Some blocks have one color, others have two, and some blocks are cubes, while others are rectangular prisms. This makes the binomial cube a more complex sensorial material, and it requires organized thinking to master. The binomial cube's big brother, the trinomial cube, is a child's more complex next step.

Like other sensorial materials, the binomial and trinomial cubes are self-correcting: when properly assembled, the blocks form a cube that fits perfectly inside of its wooden box. Even if the cube is built outside of its box, visual cues alert the child to any errors they might have made.

gotta put the tma mathposting on hold and go do responsable young adult activities. you guys should send me asks if you want

The reason I plan on being a math major is actually not bc of anything else other than when I’m stressed out numbers calm me down. They put me at ease. Like I can breathe again. Numbers.

Learning to code:

1: Oh this is fun

2: Logic mistake that breaks everything

4: aaaaaah

5: fixed it! (took three hours and an additional fifty lines)

Repeat

Unit 2 Review

1. Keep an eye on negatives (highlight)

2. Draw shit on test when bored. This helps with stress

3. Quadratic Formula: highlight a, b, c and write stuff in and out of order with highlighter

Lack of repetition makes you concentrate more

4. Completing the Square: always check with another technique (quadratic formula usually) because it’s a bastard

5. Graphing

Hope to god you don’t flip the negative to the other side of the graph

If allowed graphing calculator, PLOT IT!

Keeps you in correct quadrant

6. Check as you go by plugging in values

7. For Application problems, redo it

Minimize mental math

Do everything on calculator that you can

When solving for vertex y-value, saving 4 decimal of x-value when plugging it back into equation

8. Study enough that you can look at a problem and know roughly where to start it

9. a+bi grammar

ie. If you got a good grade, your professor will attack your grammar so if you got even a square root or a fraction, put the “i” aka imaginary number always at the end

i hate math i hope it goes fucks itself

girl help i cant math

Not me dreading math and science because I have tests and I didn’t study at all-

A perfect square trinomial. 🤓

It's a little late to post it, but I couldn't find a way to defeat Micha until now. 😌🥴 And I always sacrifice a Levi so that Mammon can live in the last horde. *Cof* *cof* I have Mammon at 70 for fear of wasting tears. *Cof* *cof.*
