Question

2x^2+5x+3
15x^2+x-6

In factor form pls

Answer 1

(x+2)(x+3)

(x-9)(x+10)

Explanation:

Using ax^2+bx+c, you need to find factors of a*c that are equal to the sum of b.

2x^2+5x+3

2*3=6 and 2+3=6 so 2x^2+5x+3 can be written as (x+2)(x+3).

15x^2+x-6

15*-6=-90, -9*10 also equals -90 and -9+10=1, so it can be written as

(x-9)(x+10).

Hope this helps!
