Identify coefficients: Identify the coefficients a, b, and c in the quadratic expression 2p2+9p+7 by comparing it to the standard form ax2+bx+c.a=2, b=9, c=7
Find two numbers: Find two numbers that multiply to a∗c (2∗7=14) and add up to b (9).The numbers that satisfy these conditions are 2 and 7 because 2∗7=14 and 2+7=9.
Rewrite middle term: Rewrite the middle term 9p using the two numbers found in the previous step.2p2+9p+7 can be rewritten as 2p2+2p+7p+7.
Factor by grouping: Factor by grouping. Group the terms into two pairs and factor out the common factor from each pair.From the first pair 2p2+2p, factor out 2p to get 2p(p+1).From the second pair 7p+7, factor out 7 to get 7(p+1).
Factor out common binomial: Now that we have 2p(p+1)+7(p+1), we can factor out the common binomial factor (p+1). The factored form is (2p+7)(p+1).
