Question

the factor of x^2 -4x-12 is_____ ​

Answer 1

$= > {x}^{2} - 4x - 12$

$= > {x}^{2} - 6x + 2x - 12$

$= > x(x - 6) + 2(x - 6)$

$= > (x - 6)(x + 2)$

Hope this answer helps you ^_^ !

Answer 2

Solution:

x²-4x -12 = 0

=> x² + 2x - 6x - 12 = 0

=> x(x + 2) - 6(x + 2) = 0

=> (x+2) (x-6) =

=> x = -2 or 6

. ' . the factor of x^2 -4x-12 is -2 and 6
