Question

factors of x^2-x-156are
​

Answer 1

Answer:

$x {}^{2} - x - 156 \\ \\ = {x}^{2} - (13 - 12)x - 156 \\ \\ = {x }^{2} - 13x + 12x - 156 \\ \\ = x(x - 13) + 12(x - 13) \\ \\ = (x - 13)(x + 12)$

Answer 2

Step-by-step explanation:

x^2 - x - 156=0

x^2 - 13x + 12x -156=0

x(x- 13) 12(x- 13)=0

(x+12)(x-13)=0

(x+12)=0 or (x-13) =0

therefore, x= -12 or x=13
