SOLUTION: Please solve the equation y=x^2+4x-6 for the variable x. I have tried to find the x values where y is equal to "0" and although these two are related, they are not the same problem

Question 842683: Please solve the equation y=x^2+4x-6 for the variable x. I have tried to find the x values where y is equal to "0" and although these two are related, they are not the same problem. I am trying to figure out how x depends on y. What is throwing me off is the x^2. I know that I have to isolate x. I have tried using the quadratic equation formula but the answers I received were wrong (x=-2+sqrt10 and x=-2-sqrt10). Any help would be appreciated. Thank you in advance.

Treat y as a constant. You can then either complete the square to find formulas for x, or you can directly use the general solution to a quadratic equation.

Again, if y is a constant, then
.
Use Completion of Square if you want, but if you know the general solution process using it, then you know how to use the result for x.
