Given the polynomial $d^{2}$ + 30d - 64 *** We break of the middle term into two factors that add to give +30 and multiply to give -64. The two numbers are +32 and -2. $d^{2}$ + 32d - 2d - 64 We take the GCD of the first two and the GDC of the last two terms. d(d+32) -2(d+32) We take (d+32) and factor it out which gives us. (d+32)(d-2)
