Question

Easy Question! Find the number that should be added to the expression to create a perfect square trinomial: x^2 − 8x

A) -64

B) -16

C) 16

D) 64

Answer 1

C

Explanation:

16

Answer 2

Answer: The answer is C

Explanation:

Well, an example of a perfect square trinomial would look like is:

`a^2-2ab+b^2` or
`a^2+2ab+b^2`

So since we already know what
`a^2` is and what
`2ab` is we just have to find
`b^2`

However, we would use the
`a^2-2ab+b^2` formula to solve this since we have a subtraction sign
