FAQ

Algebra questions, answered

The questions people actually search before reaching for a calculator.

What is the difference between an equation and an expression?

An expression is a combination of numbers, variables, and operations with no equals sign, like 3x + 5. An equation states two expressions are equal, like 3x + 5 = 11, and can be solved.

What is a variable in algebra?

A variable is a letter, such as x or y, that represents an unknown or changeable number in an equation or expression.

How do you solve a linear equation?

Isolate the variable by performing the same operation on both sides of the equation, undoing addition, subtraction, multiplication, or division in reverse order.

What is the difference between factoring and expanding?

Factoring rewrites an expression as a product of simpler terms, like turning x² + 5x + 6 into (x + 2)(x + 3). Expanding does the reverse.
