Which polynomial has factors of 4x – 7 and x + 4?

Answers

Answer from: dogwisperer101

4x² + 9x - 28.

multiply the factors together:

4x times x = 4x²

4x times 4 = 16x

-7 times x = -7x

-7 times 4 = 28

therefore, (4x-7) times (x+4) = 4x² + 16x -7x = 28

next, you must condense and simplify your

16x -7x equals 9x

your final answer should be 4x² + 9x - 28.
