Let me re-formulate your question in this form:

Solve the system of two equations

system+%28y+=++-2x%5E2+%2B+12x+%2B+2%2C%0D%0Ay+=+x%5E2+-1%29.

Is this correct re-formulation?
-------------------------------------------------------

If so,  then the right sides of these equations are the same  (because left sides are identical),  and you can write

x%5E2+-1 = -2x%5E2+%2B+12x+%2B+2.

It is a quadratic equation.

Can you solve it?
