Answer
Approach
Factor the left-hand side, then set each factor to zero.
Type any math problem — Tales solves it step by step, explaining why each step is made.
An equation, an integral, a matrix, or a worded problem — the math keyboard helps with symbols like ∫, √ and fractions.
The answer appears first, then every step with the reasoning behind it.
Every solution gets its own link — reopen it when revising, or send it to a friend stuck on the same problem.
Start with the problem you’re most stuck on.
Would you ever worry that your calculator multiplied wrong? Tales solves math the same way — with an engine that only knows how to compute, not how to guess.
Every step is real computation
The engine doesn’t write plausible-sounding text and hope it’s right. It performs each mathematical operation — the same kind of technology used in professional math software.
Honesty over polish
If it can’t solve a type of problem — geometry, for now — Tales says so plainly.
We’ve collected and organized the problem types and exam formats of school mathematics — from classroom exercises to standardized exams — into a bank of 214,000,000 problems, and Tales is test-solved against this bank. So the problem that’s stumping you has almost certainly been seen here before.
The problems you solve with symbols and numbers
From grade-6 fractions and GCDs, through high-school algebra, calculus and probability, up to university-level matrices.
Real exam formats
Multiple-choice, true/false and short-answer formats — tested directly against recent national exam papers, on the topics Tales covers.
Browse worked solutions from the bank
From grade-6 homework to university-level problems — just type it in. The main areas:
Linear & quadratic equations, polynomials, systems, inequalities, factoring, simplifying and expanding.
Derivatives, definite & indefinite integrals, limits, tangent lines, optimization.
Determinants, inverse matrices, row reduction (RREF), eigenvalues, solving linear systems.
Prime factorization, GCD and LCM, modulo and remainders, fractions and mixed numbers.
Permutations (nPr), combinations (nCr), counting, probability — including conditional probability.
Trig equations, sequences and series, logarithmic and exponential equations, worded problems.
One honest limit: geometry problems that need a figure or a proof aren’t supported yet (see the FAQ). Anything else? Just type it in.
Tales lives inside CalcES, a free online scientific calculator. Finish any calculation there and tap “Explain step by step” under the result to get the full worked explanation of the same problem — no retyping. CalcES for the answer, Tales for the why.
