Question

Factorise m^2- 14m - 32​

Answer 1

Answer:

m=-2,2

Step-by-step explanation:

${m}^{2} - 14m - 32 \\ = {m}^{2} + 2m - 16m - 32 \\ = m(m + 2) - 2(m + 2) \\ = (m + 2)(m - 2) = 0 \\ m + 2 = 0 \: \: \: \: \: \: m - 2 = 0 \\ m = - 2 \: \: \: \: \: \: m = 2$

Answer 2

Answer:

m=±2

Step-by-step explanation:

$\bf{m2−14m−32 }\\ = \bf{m2+2m−16m−32 }\\ = \bf{m(m+2)−2(m+2) }\\ = \bf{(m+2)(m−2)=0 }\\ \bf{m+2=0} \\ \bf{m−2=0} \\ \bf{m=−2 \: \: \: \: \: m=2}$
