Question

Tell Whether You Would Factor The Polynimoial By Grouping

4w^2+23w+15

Answer 1

three terms means no I would not use grouping

Answer 2

Grouping for three terms can be done as follows:
4w^2+23w+15
Find m,n such that m.n=4*15=60, and m+n=23
The obvious choice is m=20,n=3
Rewrite equation as:
4w^2+23w+15
=
4w^2+20w
3w + 15
which factorizes to
(w+5)(4w+3)
