Question

Add a constant to the following to make the expression a Perfect Square Trinomial

x2 - 8x + ___

x2 + 18x + ___ x2 - 16x + ___

all of them

Answer 1

To find the c term, the formula is (b/2)² b is the term in the middle. You should really try to do some of them on your own.

Answer 2

To find a perfect square trinomial you need to find the value of c that makes it a perfect trinomial.

In a trinomial the first number is a, which in this equation is 1. The second is b and in this equation it is 8. And the third number in this equation is c which is the number you're looking for.

To do that that you need to take b which is -8, divide -8 by 2 and square it. -8/2 ^2 = 64/4. That reduced = 16.

So your equation is x^2 -8x +16
