Question

Help with Factoring? Thanks! ~Bree :) (will post below, explanation needed if possible, thanks!)

Answer 1

2a^2 - 11a + 9
= 2a^2 - 2a - 9a + 9

Answer 2

now you can factor the above by grouping

Answer 3

Hint: take 2a out to factor the first 2 terms

Answer 4

how did you know to subtract 2a? (sorry this is on my review and it has completely slipped my mind)

Answer 5

I used the ac method
you multiply the coefficient of x^2 by the last term
here it is 2 * 9 = 18
i need 2 numbers whose product is + 18 and whose sum = middle part which is -11
so i write -2x - 9x

Answer 6

- for x read a

Answer 7

ohh okay, i think its coming back to me now, thank you!
