Percy solved the equation x2 + 7x + 12 = 12. his work is shown below. is percy correct? explain. 1. (x + 3)(x + 4) = 12 2. x + 3 = 12 or x + 4 = 12 3. x = 9 or x = 8

Sample Response: Percy is not correct because he applied the zero product property to a factored expression that was not equal to 0. He should have subtracted 12 from both sides to get x2 + 7x = 0 before factoring. The correct solutions are 0 and -7.

Percy did the wrong factorization. The correct solution of the given quadratic equation is 0 and -7 and this can be determined by using the factorization method.

Given :
