Question

Factor by grouping m^2 +8mn -3mn-24n^2
20 POINTS

Answer 1

To factor this is expression, one simple way to do this is to place brackets surrounding each set of 2 terms. Do brackets around m^2 and 8mn and brackets around -3mn - 24n^2.

Then solve for the common factor in each bracket group.

m(m + 8n) - 3n(m + 8n)

(m-3n)(m + 8n) is the answer.

Answer 2

Group and factor the GCF, then combine (m+8n) (m-3n)
