Please explain how to solve this.

The product of two consecutive even integers is 168. Find the two integers.

Hint: Assume the first integer is x

Set up the equation first that satisfies the given condition. Then solve the equation.

This is the equation that i came up with. Ican t seem to get past

x(x+2)=168

x^2+2x-168=0 (i cant get past here)

Thanks,
