Chapter 1: Simultaneous and Quadratic Equations

Practice vocabulary flashcards focused on the definitions and concepts related to simultaneous and quadratic equations as introduced in Chapter 1.

Simultaneous Equations

A set of two or more equations, each containing several variables, which are solved together to find the common values that satisfy all of them simultaneously.

Quadratic Equation

A polynomial equation of the second degree, generally expressed in the standard form $ax^2+bx+c=0$, where $a$, $b$, and $c$ are constants and $a\neq 0$.

Standard Form of a Quadratic Equation

The mathematical arrangement represented by the expression $ax^2+bx+c=0$.

Substitution Method

A technique for solving simultaneous equations by expressing one variable in terms of another from one equation and substituting that expression into the other equation.

Elimination Method

A process of solving simultaneous equations by adding or subtracting them to remove one of the variables, making it possible to solve for the remaining variable.

Variable

A symbol, usually a letter, used to represent an unknown numerical value within an algebraic equation or problem.
