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.
