Is the equation suppose to be f(x)=x^2 and g(x)= x+5^2-9? the triangle thing means to the power of
Note that the notation

is just another way of writing

. Here, we're simply taking the expression for f(x) and adding the expression for g(x) to it. Together, we have:

Which means that

And from there, it's just a matter of combining like terms to simplify.
