Answer:
Step-by-step explanation:
(f*g)(x) = (-5x² + 2x + 7) (x +1)
           = x* (-5x² + 2x + 7) + 1*(-5x² + 2x + 7)
           = x*(-5x²) + x*2x + x*7 - 5x² + 2x + 7
         = -5x³ + 2x² + 7x - 5x² + 2x + 7
         = - 5x³ + <u>2x² -5x²</u>   <u>+ 7x + 2x </u>+7   {Combine like terms}
        =  -5x³ - 3x² + 9x + 7
4) (f*g)(x) = (x² + 2x + 4)(x - 2)
                 = x*(x² + 2x + 4) - 2*(x² + 2x + 4)
                 = x*x² + x*2x + x*4 - 2*x² - 2*2x -2* 4
                 = x³ + 2x² + 4x  -2x² -4x - 8
                 = x³ - 8
