Work Step by Step

Given the polynomial $p^{2}$ - 4p + 4 *** We break of the middle term into two factors that add to give -4 and multiply to give +4. The two numbers are -2 and -2. $p^{2}$ - 2p - 2p + 4 We take the GCD of the first two and the GCD of the last two terms. p(p-2)-2(p-2) We take (p-2) and factor it out which gives us. (p-2)(p-2)
