Question

Factorize-
x²-2x-120

Answer 1

Step-by-step explanation:

x^2+10x-12x-120

x(x-10)-12(x-10)

(x-12)(x-10)

x=10,12

Answer 2

Answer:

(x+10) (x-12) are the factors of x²-2x-120

Step-by-step explanation:

To factorize quadratic polynomials we do regrouping

product= -120

sum= -2

so we get

-12 and 10

product = -12 * 10 = -120

sum= -12 + 10 = -2

we rewrite

x² - 12x + 10x - 120

x (x-12) + 10 (x-12)

(x+10) (x-12)
