Solved by pluggable solver: SOLVE quadratic equation with variable

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=169 is greater than zero. That means that there are two solutions: .

Quadratic expression can be factored:

Again, the answer is: 4, -0.333333333333333. Here's your graph:

solve by using the quadratic formula.
3x^2=11x+4
-----------
3x^2-11x-4=0
x=[11+-sqrt(121-4*3*-4]/6
x=[11+-13]/6
x=-1/3 or x=4
