I need help on these two problems please!

The answer to your question is below

Step-by-step explanation:

14a           f(x) = (2x + 2)(5 - x²)

Process

1.- Factor (5 - x²)

               (5 - x²) = (

Then        f(x) = (2x + 2) (

2.- Equal each factor to zero

               2x₁ + 2 = 0             - x₂ = 0            ₃ = 0

               2x₁ = -2                  x₂ =                 x₃ = -

                 x₁ = -2/2

                 x₁ = -1

3.- Conclusion

     The roots of the function are

      x₁ = -1

      x₂ =

      x₃ = -

14b.Expand the function

             (2x + 2) (5 - x²) = 10x - 2x³ + 10 - 2x²

or                                      -2x³ - 2x² + 10x + 10

the correct answer to your question is a. 4^4

good luck my friend!

hope this !

maybe if i you could me by giving me brainliest?

! < 3

have a splendid day < 3 : )

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
