Answer: Isolate the variable by dividing each side by factors that don't contain the variable.
x= -7, -9
Its a squared + xb squared = c squared so its 11 squared + 11 squared equals c squared. So I'm gonna take it down to the next step and say 11x11+ 11x11= c squared, then you end up with 121+121= c squared then you add those two and end up with 242= c squared, so then you find the square root of 242 so you should end up with 15.5 and the number goes on and on and on

Answer
3.14(a^2 + ab) when a = 3 and b = 4
then
3.14(3^2 + 3*4)
= 3.14(9+12)
= 3.14(21)
= 65.94
