Question

What value of c makes x2 − 12x + c a perfect square trinomial? −36 −24 24 36

Answer 1

To get the value of c that make x² - 12x + c a perfect square, we divide the coefficient of x by two then we square the answer.

The number = (-12/2)²

                    = (-6)²

                   = 36

So, the correct answer is 36


x² -12x + 36 is now a perfect square and when it is factorised it comes to:

(x - 6)²
