If ƒ(x ) = x 2 + 1 and g(x ) = 3x + 1, find [ƒ(2) - g(1)] 2 <-- is to the power of two do i solve for fx and gx first and then use the power or do i multiply the brackets inside to the power first?

If ƒ(x ) = x 2 + 1 and g(x ) = 3x + 1, find [ƒ(2) - g(1)] 2 <-- is to the power of two do i solve for fx and gx first and then use the power or do i multiply the brackets inside to the power first?
\([f(x)-g(x)]^2 \)
\(=[f(1)-g(2)]^2\)
\(=[(1^2+1)-(3\cdot2+1)]^2 \)
\(=[2-7]^2\)
\(=[-5]^2\)
\(=25\)
Do solve for fx and gx first and then use the power.
