Could someone please help me with this problem. I have worked most of it out but now I'm not sure what to do.
Multiply ans simplify.
(x9/4)(x+4/9)
Here is what I have so far:
x(x+4/9)9/4(x+4/9)=
x^2+4/9x9/4x9/44/9=
x^2+4/9x9/4x1=
This is where I'm not sure what to do.
Could someone please help?
Thanks.

PsyDAG,
Find common denominator to combine terms.
x^2 + 16/36x  81/36x  1.
Does that help?
