The roots of the quadratic x^2+8x+4 are the same as the roots of the quadratic Ax^2+Bx+1. What is A + B?

A + B = 1/2 + 4 = 9/2.

That is incorrect. Try to explain how you got 1/2 and 4.

We will divide all of these by 4..

1/4x^2+2x+1

A=1/4

B=2

So, A+B=2.25.

Yep! That's the same answer that I got. Good job!

Hmm...

I think what Guest meant to do was divide the first quadratic by 4, which gets us

$$\frac{1}{4}x^2+2x+1$$

a=1/4

b=2

So add them up and get

1/4+2=9/4, or 2.25
