Week 10 – Math 10

Week 10 in Math 10…

This week was factoring polynomials and atbthe beginin it was a lot to take in but by the end I think i got the hang of it.

It really helped when Ms.Burton showed us we can factor usin an Area Model and it was a lot easier for me.

I have drawn out the steps to find the factors of an expression:

This shows the first step, you are given an expression…

(What i’m showing will only work if it looks like this; x to the power of 2/ squared and the middle is a number followed by x and then the last just a constant term or a number with no variable or degree.)

the next step is to list the factors of the constant (in yellow.) then find the one that fits best for the sum of the middle number. place the x squatted in the top left and the constant in the bottom right box then the two numbers that add to 21 in the remaining.

Solve for what the highest number or variable is that you can take out of each two boxes. I have shown arrows and then the answers.








Now the numbers on the outside is your answer, all the factors of the first expression. Therefore your answer is….
