Question

factories x2 - 4x - 12​

Answer 1

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

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

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

= (x+2)(x-6)

Answer 2

Step-by-step explanation:

$\sf \bf We \: have,$

$\sf x^2-4x-12$

$\sf : \implies x^2-6x+2x-12$

$\sf : \implies x(x-6)+2(x-6)$

$\sf : \implies (x-6)(x+2)$

So, the factors of the quadratic polynomial x²-4x-12 are (x-6) and (x+1).
