What kinds of algebra problems can it solve?

Linear, quadratic, polynomial, rational, radical, exponential and logarithmic equations; systems of equations; inequalities; and simplifying, expanding or factoring expressions.

How do I enter exponents and fractions?

Use ^ for powers (x^2) and / for fractions ((x+1)/(x-2)). You can also paste LaTeX such as \frac{1}{2} or use the math keyboard.

Are the answers checked?

Yes. Equation solutions are substituted back into the original equation and simplifications are compared numerically with the original expression.

Algebra Calculator

Type any algebra problem — an equation, an expression to simplify, or a polynomial to factor — and get an exact answer with every step explained. Each result is independently verified by substitution or numerical checks before it is shown.

How to use the algebra calculator

Enter your problem using the keyboard or the math keypad (use ^ for powers).
Add a command like “simplify”, “factor” or “expand” if you want a specific form.
Press Solve to see the answer, each step, the formulas used and the verification.

Examples

3(x - 2) + 4 = 2x + 7

Answer: x = 9

Distribute, collect like terms, isolate x.

simplify (x^2 - 9)/(x - 3)

Answer: x + 3, x ≠ 3

factor 2x^2 + 7x + 3

Answer: (2x + 1)(x + 3)

Formulas

Difference of Squares

a^{2} - b^{2} = (a - b) (a + b)

Quadratic Formula

x = \frac{- b \pm b ^{2} - 4 a c}{2 a}
