The first equation, just set the expression equal to zero and solve.

The second equation, since not factorable, use Completing the Square. The term needed is %285%2F2%29%5E2. You can avoid Completing the Square and just take its result using the general solution....

x=%28-5%2B-+sqrt%285%5E2-4%2A1%2A%28-1%29%29%29%2F2

highlight%28x=%28-5%2B-+sqrt%2829%29%29%2F2%29
