Answers:
- A variable in algebra is a symbol that represents a number. It is usually represented by a letter, such as x or y.
- An equation has an equal sign and requires a solution, while an expression does not have an equal sign and does not require a solution.
- A quadratic equation is an equation in which the highest power of the variable is 2 (e.g. ax^2 + bx + c = 0).
- To solve a system of linear equations, you can use the substitution method, the elimination method, or graphing.
- The order of operations in algebra is parentheses, exponents, multiplication and division (performed from left to right), and addition and subtraction (performed from left to right).
