How to use it

Type a normal equation with an = sign and press Solve. The tool looks at what you typed and automatically picks the right method — you don't choose a mode.

One equation, one letter — any degree

Use ^ for powers. It finds every solution, including complex ones.

A system of equations — many letters

Put each equation on its own line, or separate them with commas. Use any letters you like.

Coefficients box

If you already have the numbers, type them highest-power first: 1 -6 11 -6 means x³ - 6x² + 11x - 6 = 0.

What it can do

Single polynomial equations to any degree · systems of linear equations (up to 12 unknowns) · detects "no solution" and "infinitely many solutions" and names the free variables.

What it can't do

It can't solve equations with a function wrapped around the letter, like sin(x) = 0.5 or 2^x = 10. For those, plot both sides on Graph and read where they cross. Systems must be linear (no x*y or x^2).
