WORKED EXAMPLES

See How It Works

Linear equation: 2x + 6 = 14. Subtract 6 from both sides to get 2x = 8. Divide both sides by 2 to get x = 4. Check: 2 × 4 + 6 = 14, so the answer is correct.

Quadratic equation: x² − 5x + 6 = 0. Here a = 1, b = −5 and c = 6. The discriminant is (−5)² − 4 × 1 × 6 = 1. It is positive, so there are two real solutions. x = (5 ± 1) ÷ 2, so x = 3 or x = 2.

Type either problem into the solver above to see the same steps.

THE BASICS

What Is a Maths Problem Solver?

A maths problem solver takes the problem you type and shows how to reach the answer. It is most useful for checking homework, spotting where a step went wrong and seeing a method you can copy onto paper.

The box above handles arithmetic, linear equations and quadratic equations in x. For other topics, use the specialist solvers. Try each problem yourself first, then compare your working with the steps.

For wider revision, see the maths and stats resources from London South Bank University Library. You can also get one-to-one help from our homework helper or maths tutor pages.

QUICK ANSWERS

Maths Problem Solver FAQ

What can the Maths Problem Solver solve?

The box handles arithmetic, linear equations and quadratic equations in x. For algebra, inequalities, fractions, trigonometry, calculus and graphs, use the specialist solvers linked on this page.

Does it show the steps?

Yes. Each answer comes with short steps, such as moving terms to one side or working out the discriminant, so you can follow the method.

How do I type powers and fractions?

Write x^2 for x squared and use / for division, for example (x + 1) / 2. Use * for multiplication, although 2x and 3(x + 1) also work.

Is the solver free?

Yes. It is free to use, with no sign-up needed.

Can I use it to check my homework?

Yes. Try the problem on paper first, then compare your answer and working with the steps. Your teacher will still want to see your own method.

Why does it say my equation is too advanced?

The box only solves equations that work out to linear or quadratic form in x. Equations with x in a denominator or with powers above 2 need a specialist solver.
