    multiply, the same way you would if you were dealing with two digits pick only 1 term, multiple times all others on the other group pick another term, and do the same then simplify

    f(x) and g(x) into (f)(g)(5) is multiplying right? You don't mean f(g(x))? If not, you multiply the equations while inputting 5 for x. 4(5) + 3 times -2(5) + 5.

    (a + b) * (c + d) a * c a* d then b * c b * d add them up, simplify

    \(\bf f(x) = 4x + 3 \qquad g(x) = -2x + 5 \\ \quad \\ (f)(g)(5)\implies f({\color{brown}{ 5}})\cdot g({\color{brown}{ 5}})\implies (4({\color{brown}{ 5}})+3)\cdot (-2({\color{brown}{ 5}})+5) \) even simpler
