Answer:
[tex]2 {x}^{3} + 1.5 {x}^{2} - 5x[/tex]
Step-by-step explanation:
Multply f(x)*g(x)
((x/2)/2)*(2x^2+x-3)
First get (f+g)
f+g=(x/2)-2)+(2x^2+x-3)
multply all eqn by 2
2(f+g)= x -4+4x^2+2x-6
2(f+g)= 4x^2+3x-10
devide by 2
(f+g) = 2x^2 + 1.5x -5
(f+g)(x) =
[tex]2 {x}^{3} + 1.5 {x}^{2} - 5x[/tex]
