Step-by-Step Solver
The whole working out, beside the graph. Designed for revising students who need to understand why, not just see a final answer.
Three views of the same problem — the equation, every reasoning step, and a graph of both sides. Designed for students who need to see why, not just the final answer.
Worked steps
Graph (LHS − RHS)
Each x-intercept of this curve is a real solution.
Reading the graph
The graph shows LHS − RHS. Wherever that curve crosses the x-axis, the equation LHS = RHS has a real solution. So if you type x² − 4 = 0, the graph will be a parabola dipping below zero between x = −2 and x = 2 and crossing the axis at exactly those two values. That visual matches the symbolic answer the steps panel computes.
When the graph misses a root
The graph window auto-fits around the real roots, but the equation may also have complex roots that do not show up on the curve. The step-by-step panel still reports them in a ± bi form. If you see "two complex roots" in the steps but the curve does not touch the axis, that is the explanation — the parabola sits entirely above (or below) zero.
Use it as a tutor
The biggest gain from this tool is the ability to compare your own working against the canonical sequence. Solve the problem on paper, then check each line against the steps panel. Where the two diverge is exactly where you went wrong — and you have a worked-through example of how it should have gone.
