Refer to picture.

Answer 5

Always good to start by drawing a picture. So that is the picture and the frame. How can we figure out how much area the frame has?

Answer 6

would it be (x2-3*x2-3)-(x*x)=27

Answer 7

Yes =) But be careful with parenthesis. It's (x^2-3)(x^2-3). That's different from (x^2-3*x^2-3)

Answer 8

So now just simplify and solve the equation for x.

Answer 9

x=3,-3
