f s(x) = 2x^2 + 3x - 4, and t(x) = x + 4 then s(x) · t(x) =

Step-by-step explanation:

  A) 2x³ + 11x² + 8x - 16

Step-by-step explanation:

s(x) · t(x) = (2x² + 3x - 4)(x + 4)

             = x(2x² + 3x - 4) + 4(2x² + 3x - 4)

             = 2x³ + 3x² - 4x   + 8x² + 12x - 16

             = 2x³ + 3x² - 4x   + 8x² + 12x - 16

             = 2x³ + 11x² + 8x - 16
