Question

4. The factors of the following expression are
x2 + 4x - 32
(x + 4) (x – 8)
(x – 4) (x + 8)
(x + 4) (x + 8)
(x – 4) (x – 8)​

Answer 1

Answer:

Given quadratic equation is x² −4x−32

It can be factorised by splitting the middle term as

x²

−4x−32=x²

−8x+4x−32

=x(x−8)+4(x−8)

=(x−8)(x+4)

Thus factors are x−8,x+4.
