The quadratic equation is quick and easy to solve, especially if you use our quadratic formula calculator. But sometimes, you can solve your equation even faster using other methods.

### C Term = 0

For example, if you have the equation:

x^{2} + 4x = 0

In other words, your c term is equal to zero and you can see right away that one solution is x = 0. You then divide both sides by x, leaving you with:

x + 4 = 0

So, x = -4 is your other solution.

You could have arrived at the same answer using the quadratic formula, but it may have taken you longer.

### Factoring

Furthermore, if your second-order equation is easy to factor or

that's often a better way to solve it.

For example, if your equation were:

x^{2} - 3x + 2 = 0

You could factor it to:

(x-1)(x-2) = 0

And your solutions would be x = 1 and x = 2.

But of course, you need to have experience factoring polynomials. If that's not something you know how to do, you can always use the quadratic equation.
