Factor w2 + 8w + 16, if possible. if the polynomial is prime, say sofactor 3y2 + 10y + 7, using the ac method. if the polynomial is prime, say so.

when we compare the given equation to

a=1, b=8,c=16

So, ac=1*16=16 and b=8

We need factor pair of ac, 16, which sum upto b, 8.

As, 4*4=16 and 4+4=8

4 and 4 are required factor pair.

So,=

when we compare the given equation to

a=3, b=10,c=7

So, ac=3*7=21 and b=10

We need factor pair of ac, 21, which sum upto b, 10.

As, 3*7=21 and 3+7=10

3 and 7 are required factor pair.
