Are you a student, educator or professional who has to solve equations often?
Are you tired of proving again and again that you know how to solve a quadratic?
If so, this application might be right for you.

Students learn how to solve first order equations in elementary school and quadratics in high school.
At university level, polynomial equations are widely used in math, physics, chemistry, economics, engineering etc.
They are usually of higher order and require a numerical solution.

Solving polynomial equations is a tedious task either using an algebraic solution or a numerical one.
Poly Solver finds the roots (real and complex) of most polynomial equations of degree up to 20 in a fraction of a second.
It's easy to use. Enter the coefficients of the polynomial, separated by commas, and tap the zipper.

To solve 2x-8=0, type 2,±8 or 2,8±
To solve x²-x-1=0, type 1,±1,±1
To solve x³+6x-20=0, type 1,0,6,±20 or 1,,6,±20
To solve x⁴+3x²-4x=0, type 1,0,3,±4,0 or 1,,3,±4,
To solve x⁵+1=0, type 1,0,0,0,0,1 or 1,,,,,1 (5 commas)
