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
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
