Rewrite the middle term as the sum of two terms and then factor completely.
4z^3 - 18z^2 10z First factor out the GCF 2z
a=2, b=-9, c=-5
Replace the middle coefficient with two numbers that multiply to get ac, but add to get b.
ac=2(-5)=-10
-10(1)=-10
-10+1=-9
Group the first two and last two terms.
Factor out the GCF from each group.
Factor out the GCF (z-5)
Happy Calculating!!!
