Standard Form of a Linear Equation
The standard form for a linear equation is detailed.
Square Roots of Decimal Numbers and Perfect Square Decimals
Finding the square root of a decimal is discussed, noting that any decimal that does not have an even number of places after the decimal cannot have an exact square root.
Solving Quadratic Equations When Both Sides are Perfect Squares
Solving an equation in which both sides are perfect squares does not require putting the equation into standard form.
Quadratic Equations in Standard Form
The standard form for a quadratic equation is ax2 bx = 0. It is not always clear whether an equation is a quadratic equation until it is simplified. Any equation that can be written in stand form is a quadratic equation.

Multiplying Two Factors with the Same Base
The rules for exponents begin with the rule for multiplying two factors with the same base.
Introduction to Factoring Quadratic Trinomials
A quadratic trinomial is a polynomial with three terms. In two of the terms the same variable appears, one that is raised to the second power and the other with an exponent of one. The third term in a quadratic trinomial is a constant. To factor a q...
