5x^{2}-7x-7x=5x^{2}
Subtract 7x from both sides.
5x^{2}-14x=5x^{2}
Combine -7x and -7x to get -14x.
5x^{2}-14x-5x^{2}=0
Subtract 5x^{2} from both sides.
-14x=0
Combine 5x^{2} and -5x^{2} to get 0.
x=0
Product of two numbers is equal to 0 if at least one of them is 0. Since -14 is not equal to 0, x must be equal to 0.
