I don't understand these I need help

Answer 1

F(x) . g(x) means that you have to multiply both functions.

This is how you do it:

$\frac{4x^2 + 6}{2}. \frac{3}{2x^2+3} = \frac{2(2x^2+3).3}{2.(2x^2+3)}= 3$

Note that I have simplified the expressions that are common in the numerator and denominator.
