Key Concepts

Polynomial Equations

Polynomial equations are equations where the variable is raised to a whole number power and combined using addition, subtraction, and multiplication. Techniques such as factoring and applying the zero product property are fundamental to solving these types of equations.

Handling Constant Multipliers

When an equation includes a non?zero constant multiplying a product of factors, the constant does not affect the solutions of the equation. Only the factors containing the variable are set equal to zero because a non-zero constant multiplied by zero is still zero.

Zero Product Property

The zero product property states that if a product of factors equals zero, then at least one of the factors must be zero. This principle is used to solve equations that have been factored; once the equation is expressed as a product, you set each individual factor equal to zero to solve for the variable.

Factoring

Factoring involves rewriting an expression as a product of simpler expressions. In polynomial equations, factoring is a key technique used to simplify the problem and to reveal the factors to which the zero product property can be applied.
