Which polynomial has factors of 4x - 7 and x + 4?
3x² + x - 3
4x² + 9x - 28
3x² - 7x - 3
4x² - 23x - 28

Solution:

Given factors (4x - 7) and (x + 4)

Multiplying the factors using the distributive property, we get

⇒ 4x(x) + 4(4x) - 7(x) - 7(4)

⇒ 4x² + 16x - 7x - 28

⇒ 4x² + 9x - 28

Therefore, 4x² + 9x - 28 is the polynomial which has factors 4x - 7 and x + 4

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

Summary:

4x² + 9x - 28 polynomial has factors of 4x - 7 and x + 4.
