Answer:
1
Use the sum-product pattern
2−4−12
m^{2}{\color{#c92786}{-4m}}-12m2−4m−12
2+2−6−12
m^{2}+{\color{#c92786}{2m}}{\color{#c92786}{-6m}}-12m2+2m−6m−12
2
Common factor from the two pairs
2+2−6−12
m^{2}+2m-6m-12m2+2m−6m−12
(+2)−6(+2)
m(m+2)-6(m+2)m(m+2)−6(m+2)
3
Rewrite in factored form
(+2)−6(+2)
m(m+2)-6(m+2)m(m+2)−6(m+2)
(−6)(+2)
(m-6)(m+2)(m−6)(m+2)
Solution
(−6)(+2)
