Question

factorise:m2+5m+6
(2=square)

Answer 1

${m}^{2} + 5m + 6 = 0 \\ \\ {m}^{2} + 2m + 3m + 6 = 0 \\ \\ m(m + 2) + 3(m + 2) = 0 \\ \\ (m + 2)(m + 3) = 0 \\ \\ m = - 2 \: \: \: \: \: \: or \: \: \: \: m = - 3$
Hope it helps you.

Answer 2

m²+5m+6=0
m²+3m+2m+6=0. (2×3=6)
m(m+3)+2(m+3)=0
(m+3)×(m+2)=o
m=-3,-2
