Question

Factorise the following
m^2+4m-32​

Answer 1

Answer:

(m - 4) (m + 8)

Step-by-step explanation:

m^2 + 4m - 32

We will need two such numbers whose sum is 4 and product is -32. Those numbers are -4 and 8.

= m^2 - 4m + 8m - 32

= m(m - 4) + 8(m - 4)

=(m - 4) (m + 8)

Answer 2

Step-by-step explanation:

$m ^{2} + 4m - 32 \\ m ^{2} + 8m - 4m - 32 \\ m(m + 8) - 4(m + 8) \\ (m - 4) \: (m + 8) \\ m = 4 \: or \: m \: =- 8$
