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=109 is greater than zero. That means that there are two solutions: .

Quadratic expression can be factored:

Again, the answer is: 2.90671775148509, -0.573384418151758. Here's your graph:

3y^2-7x-5=0
using the quadratic equation:
y=(7+-sqrt[-7^2-4*3*-5])/2*3
y=(7+-sqrt[49-60])/6
y=(7+-sqrt109)/6
y=(7+-10.44)/6
y=(7+10.44)/6
y=17.44/6
y=2.907 answer.
y=(7-10.44)/6
y=-3.44/6
y=-.573 answer.
