Example · (a+b)² Expansion
(a+b)² = a² + 2ab + b²
(3+4)² = 3² + 2(3)(4) + 4²
(3+4)² = 9 + 24 + 16
(3+4)² = 49 ✓

Everything you need to know.
What is EasyEquations?
EasyEquations is a free online math solver that gives you step-by-step working for algebraic identities like (a+b)², (a−b)³, and factorisation formulas, as well as electronics equations like Ohm's Law and resistance calculators.
Is EasyEquations completely free?
Yes — 100% free, with no registration, no subscription, and no ads interrupting your work.
Which formulas does EasyEquations solve?
EasyEquations covers: (a+b)², (a−b)², (a+b)³, (a−b)³, a²−b², a³−b³, x+y=z, x−y=z, Series Resistance, Parallel Resistance, and Ohm's Law (V=IR).
Can I use it on my phone?
Absolutely. The app is fully responsive and works on any device — smartphone, tablet, or desktop — without any installation.
How does the step-by-step solver work?
You enter values for the variables (e.g., a = 3, b = 4), press Submit, and EasyEquations shows every intermediate step — from substitution through simplification — so you can follow and learn the method.
Is this useful for Class 9–12 students?
Yes. The algebraic identity solvers directly map to the CBSE / ICSE algebra curriculum, and the electronics solvers align with physics practicals in Class 10–12.
