Factorising m2 + 7m - 60 and dividing it by (m - 5) gives ___________ .
4(m-6)
2(m+6)
(m+12)
None of these
m2 +7m - 60 = m2 + 12m – 5m – 60 = (m - 5)(m + 12)
Dividing by (m−5), we get (m+12).
Divide m2+7m−60 by (m−5).
Find the value of m2+7m−60 when m=−3
Factorising m2+7m−60 and dividing it by (m−5) gives ___
