Factoring calculator online to factor trinomials, polynomials and other expressions. Prime factorization calculators and widgets.
f(x)=y

$\lim_{x \to \infty} \exp(-x) = 0$

$f(n) = n^5 + 4n^2 + 2 |_{n=17} \,$

This is how to factor quadratic equations manually:
1. Find the roots – x1 and x2
2. Then put the roots in the following expression: a(x-x1)(x-x2)=0
3. Viola… you have factored your equation.

The following factoring quadratics calculator automates this for you and does all the work to show you the result.

### The Factoring Calculator

1. First, enter the quadratic equation you would like to factor.

 X2 +– X +– = 0

Round to thousandths?Yes

The Solution Will Appear Here!

Simply enter your quadratic formula, hit the button and you will see it factored…

What is this? Nothing that special, to factor a quadratic equation like this: -4x2+4x+8 = 0 ,
means to convert it into the following form:
-4(x +1) (x -2) = 0

Converting a quadratic equation from standard form – ±ax2±bx±c=0 into a factored form, is usually done with the help of the formula:
a(x-x1)(x-x2)=0 , where x1 and x2 are the roots of the equation and ” a ” is the number in front of x2.

So to factor a quadratic equation you need:

1. To solve it
2. To use the formula from above, where to replace x1 and x2 with the roots you have found and ” a ” with the number in front of x2, in this case ( -4 ).
But solving equations could be a boring task, that’s why you can simply use our simple calculator, or our advanced one HERE. It’s much more cooler, it can draw you a chart, show you much more information about your function and has many more options you can take advantage of.

Lol, this is a great tool. Especially if you are 8th grade 🙂 and have some quadratic formula homework. I will definitely use it for mine.

Nice to hear that this is of good use to you, Noble. Tell us if you have any ideas about how we can make it better. Thanks!

• Das Mathematik-Führer says:

you shouldn’t restrict your calculator to only the answerable format. for example.

2a^2- 11a+ 15 = 2(x -3)(x -2.5) = 0

But we both know in a more realistic form it should be factored to

(x-3)(2x-5)

I advise you change/ update the programs’ software to this availability, you’ll certainly have happier users.
