Which expression is equal to the polynomial below?

2x4 5x3 - 8x - 20

x3 (2x 5) 4 (2x - 5)

x3 (2x 5) - 4 (2x 5)

x3 (2x - 5) - 4 (2x - 5)

x3 (2x 5) 4 (2x 5)

If you would like to find the equal expression to the polynomial 2x^4 + 5x^3 - 8x - 20, you can do this using the following steps:

2x^4 + 5x^3 - 8x - 20 = x^3 * (2x + 5) - 4 * (2x + 5)

The correct result would be x^3 * (2x + 5) - 4 * (2x + 5).
