ANSWER:

[tex]8x^2-21x-1[/tex]

STEP-BY-STEP EXPLANATION:

We have the following functions:

[tex]\begin{gathered} f(x)=-2x^2+4x+1 \\ g\mleft(x\mright)=5x-3 \end{gathered}[/tex]

We replace the operation between functions, and we would have:

[tex]\begin{gathered} -4f(x)-g(x) \\ -4\cdot(-2x^2+4x+1)-(5x-3) \\ 8x^2-16x-4-5x+3 \\ 8x^2-21x-1 \end{gathered}[/tex]
