use the quadratic formula to solve for this equation: 2a^2-46a+252=0
-----------------
a^2 - 23a + 126 = 0 Divide it by 2

Solved by pluggable solver: SOLVE quadratic equation (work shown, graph etc)

Quadratic equation (in our case ) has the following solutons:

For these solutions to exist, the discriminant should not be a negative number.

First, we need to compute the discriminant : .

Discriminant d=25 is greater than zero. That means that there are two solutions: .

Quadratic expression can be factored:

Again, the answer is: 14, 9. Here's your graph:

-------------
The solver uses x, just make that a
a = 9
a = 14
