What this calculator solves
The solver covers common one-variable linear, quadratic, absolute-value, rational, and square-root equations within clearly defined supported forms.
Linear equations
Solve forms such as 2x + 5 = 15 and -2x + 4 = 10.
Variables on both sides
Collect x terms from equations such as 5x - 3 = 2x + 12.
Parentheses
Expand and simplify equations such as 3(x + 2) = 18.
Constant fractions
Solve linear equations such as x/3 + 5 = 12 when denominators are constants.
Quadratic equations
Solve quadratics with real or complex roots, then inspect the discriminant, vertex, axis of symmetry, and graph.
Absolute value equations
Split supported forms such as |2x - 5| = 9 into linear cases and verify the roots.
Rational equations
Handle supported linear numerators and denominators, keep domain restrictions visible, and verify candidates.
Radical equations
Solve supported square-root equations and reject extraneous roots after squaring.
How to use the calculator
Type or paste an equation, solve it, inspect the transformations, and use verification and the graph instead of relying on the final value alone.
2. Solve for x
The dispatcher identifies the supported equation class and applies the matching linear, quadratic, absolute-value, rational, or radical method.
3. Check the answer
Numeric answers are checked against the original equation. Rational exclusions and radical extraneous roots are filtered before a candidate is accepted.
More ways to work with an equation
I added visual and input tools for the moments when a plain text answer is not enough.
Graph the equation
Plot both sides and use their intersections as a visual check on the algebraic solutions.
Paste LaTeX
Use common LaTeX fractions, roots, and powers, then review the normalized equation in a MathML preview.
Scan a photo
Use browser-side OCR as a draft transcription, review the recognized equation, and only then solve it.
Transparent browser-side workflow
The solver itself runs in your browser. Shareable ?q= URLs include the equation, recent equations use local storage, and optional image OCR loads browser-side recognition assets only when requested.
Current solver scope
Cubic and higher-degree polynomials, logarithmic, exponential, trigonometric, nested-radical, and multiple-absolute-value equations remain outside the supported solver scope.
