Answer:

[tex]24x^3-19x^2-62x+45[/tex]

Step-by-step explanation:

[tex]f(x)=-3x+5[/tex]

[tex]g(x)=-8x^2-7x+9[/tex]

[tex]f(x)*g(x)=(-3x+5)(-8x^2-7x+9)[/tex]

[tex]=(-3x)(-8x^2)+(-3x)(-7x)+(-3x)(9)+(5)(-8x^2)+(5)(-7x)+(5)(9)[/tex]

[tex]=24x^3+21x^2-27x-40x^2-35x+45[/tex]

[tex]=24x^3-19x^2-62x+45[/tex]
