Factor out GCF: Factor out the GCF from the quadratic expression. 8(v2−8v+12)
Find two numbers: Look for two numbers that multiply to give ac (product of a and c in av2+bv+c) and add to give b. For v2−8v+12, we need two numbers that multiply to 12 and add to −8. The numbers are −6 and −2.
Rewrite middle term: Rewrite the middle term using the two numbers found.8(v2−6v−2v+12)
Factor by grouping: Factor by grouping.8((v2−6v)−(2v−12))
Factor common factors: Factor out the common factors in each group. 8(v(v−6)−2(v−6))
Factor common binomial: Factor out the common binomial factor.8(v−6)(v−2)
