Question

Factor out the GCF from each term in the expression
3. 30w5 + 25w3
4. 3x(7x + 1) – 2(7x + 1)

Answer 1

factor each
30w^5=2*3*5*w*w*w*w*w
25w^3=5*5*w*w*w
gcf is 5*w*w*w

30w^5+25w^3=5w^3(6w^2)+5w^3(5)=5w^3(6w^2+5)



4.
7x+1 is factor
remember
ab+ac=a(b+c)
so
(7x+1)(3x)+(7x+1)(-2)=(7x+1)(3x-2)
