Identify coefficients: Identify the coefficients a, b, and c in the quadratic expression 2w2+13w+11 by comparing it to the standard form ax2+bx+c.a=2, b=13, c=11.
Find suitable numbers: Find two numbers that multiply to a∗c (which is 2∗11=22) and add up to b (which is 13).The numbers that satisfy these conditions are 2 and 11 because 2∗11=22 and 2+11=13.
Rewrite middle term: Rewrite the middle term 13w using the two numbers found in the previous step.The expression becomes 2w2+2w+11w+11.
Factor by grouping: Factor by grouping. Group the first two terms together and the last two terms together.This gives us (2w2+2w)+(11w+11).
Factor out common factors: Factor out the greatest common factor from each group.From the first group, factor out 2w, which gives us 2w(w+1).From the second group, factor out 11, which gives us 11(w+1).
Final factored form: Notice that both groups now have a common factor of w+1. Factor out the common factor to get the final factored form. The expression becomes 2w+11)(w+1.
