7x + 28x² - 35x³

Let's place it in descending order:

-35x³ + 28x² + 7x

Factor out -7x

-7x(5x² - 4x - 1)

The trinomial in the parentheses factors

-7x(5x + 1)(x - 1)

7x+%2B+28x%5E2+-35x%5E3
7x%281+%2B+4x+-5x%5E2%29....replace 4x with -x%2B+5x
7x%281+-x%2B+5x+-5x%5E2%29...group
7x%28%281+-x%29%2B+%285x+-5x%5E2%29%29
7x%28%281+-x%29%2B+5x%281+-x%29%29
7x%28%281%2B+5x%29%281+-x%29%29
