Question

Factorise x^2-4x-32 please

Answer 1

(x - 8) (x + 4)

Explanation:

x^2-4x-32

Consider the form x^2+bx+c. Find a pair of integers whose product is c

and whose sum is b. In this case, whose product is −32 and whose sum is −4.

-8,4

Write the factored form using these integers and we get the answer

(x - 8) (x + 4)
