Solve equation using thequadratic formula
27x^2 + 36x + 12 = 0
It helps to reduce it first
9x^2 + 12x + 4 = 0
----------------
Using the quadratic formula eliminates "steps", you just plug in the values for a, b and c into the formula.
In the example above:
a = 9
b = 12
c = 4

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=0 is zero! That means that there is only one solution: .
Expression can be factored:

Again, the answer is: -0.666666666666667, -0.666666666666667. Here's your graph:

---------------
If the coeff of the x^2 is not one, the solver gets the factoring wrong. Ignore that.
The answer is:
-2/3
