x2-35x+300 = 0 (x-15)(x-20) = 0 x = 15 or x = 20
Factor: x3 - 12x2 + 35x 1. Factor out a x: x(x2 - 12x + 35). 2. Factor x2 - 12x + 35 which is (x-5)(x-7). 3. Answer: x(x-5)(x-7).
35x + 115 = 360 35x = 360-115 35x = 245 x = 245/35 x = 7
Factor out an X X(X^2 - 12X + 35) factor quadratic equation X(X - 7)(X - 5) ------------------- fully factored
