please help. No spam..

Step-by-step explanation:

Given equation is:

Factoring it by mid-term break method.

+4x × -5x = -20x² (multiplication of side terms)

-5x + 4x = -x (Middle term)

Hence, we can split -x into -5 and +4

Either:

x - 5 = 0       OR       x + 4 = 0

x = 5             OR       x = -4

Solution Set = {5,-4}

Hope this helped!
