Question

7x^2– 19x – 6

How do I factorize this expression?

Answer 1

x = 3 and x = -2/7

Explanation:

you can multiple -6 by 7 = -42

and then find what adds into -19 but can multiply together to get -42.

In this case (x-21)(x+2) would work

then you have to divide out your 7 from both numbers,

(x-21/7)(x+2/7)

then you have to make them equal to zero

x-21/7 = 0 = x = 21/7 = 3

x+2/7 = 0 = x = -2/7

so your final answer is x = 3 and x = -2/7

Answer 2

This is the answer
I am not sure so sorry if it is wrong
