Simplifying Radicals
When simplifying square roots, we give the positive and negative answer if solving an equation that did not originally have a square root. Otherwise, we give only the principal root. Square roots of...
Solving Equations with Variables on Both Sides
It takes practice and a few useful methods to decide where to start when solving equations with a variable on both sides of the equals sign. There are many methods we use to solve for the variable when it...
Factoring Trinomials, a=1
When you are given a trinomial, or a quadratic equation, it can be useful to factor the equation for the purposes of canceling and simplifying. Factoring trinomials is easiest when the leading coefficient...
Graphing Linear Equations- Table of Values
We often use a table of values to plot and connect points when we are graphing a line. Sometimes graphing lines using an equation involves the same methods as using a table of values. There are several...
Probability, Introduction to Statistics
It can be convenient to calculate the likelihood of an event, and in many cases we can use statistical probability. We often encounter this in problems involving card games or dice rolling. We can also use...
Solving Radical Equations
Radical equations are equations that have square root terms. Learn to solve radical equations by isolating the radical on one side of the equation, and then square both sides (it is the inverse operation of...
Factoring Quadratic Equations
To solve a quadratic equation by factoring, you set one side of the equation equal to zero and use the zero product property to factor the equation. Other ways to factor a quadratic equation are completing...
Solving Quadratic Equations Using Square Roots
Solving quadratic equations using square roots works best under special circumstances. If your equation does not have a “b” term this technique may be a good one for you to try. Keep in mind...
Introduction to Systems of Equations
Systems of equations are concepts that first show up in Algebra I. Systems of equations are problems with two or more equations that contain the same variables. There are four methods to solving systems of...
Solving Single Step Equations
An important introduction to solving algebraic equations is learning how to handle single step equations. This is the fundamental building block needed to solve more complicated equations. Solving...
