Start with the first function.

Plug in .

Square to get .

Multiply and to get .

Multiply and to get .

Combine like terms.

-------------------------------------------

Now move onto the second function.

Plug in

Plug in on the right side.

Multiply 32 and 5 to get 160

Add 160 to 7 to get 167.

So the solution is
