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.

• Thanks for your advice! You are right, the form you offer is probably more convenient in some cases, but mine and yours, they are both correct. However, I will see what I can do about this issue…
