Q1. The answer is 4(2x - 3)(2x + 1)

16x² – 16x – 12 = 4 * 4x² - 4 * 4x - 4 * 3 =
                          = 4(4x² - 4x - 3) =
                          = 4(4x² + 2x - 6x - 3) = 
                          = 4(2x * 2x + 2x - (2x * 3 + 3)) =
                          = 4(2x(2x + 1) - (3(2x + 1))) =
                          = 4((2x + 1)(2x - 3)) =
                          = 4(2x - 3)(2x + 1)


Q2. The answer is 3(x + 8)(x - 1)

3x² + 21x – 24 = 3 * x² + 3 * 7x - 3 * 8 =
                         = 3(x² + 7x - 8) =
                         = 3(x *x - x + 8x - 8) =
                         = 3((x(x - 1) + 8(x - 1)) =
                         = 3(x + 8)(x - 1)

Use the functions a(x) = 3x + 10 and b(x) = 2x − 8 to complete the function operations listed below.
Gnoma [55]
For part A, you simply add the two functions a(x) and b(x). The resulting function is then (a+b)(x) = 5x +2.

For part B, you multiply the functions a(x) and b(x). Using the FOIL method, we obtain, 6x^2 -24x + 20x - 80. Simplifying, we get, (a*b)(x) =  6x^2 -4x - 80.

For part C, you replace x in the function a(x) with the expression from b(x). This results to: a[b(x)] = 3(2x - 8) +10. Simplifying, a[b(x)] = 6x - 14.
