## Solve Literal Equations

A literal equation is one in which some or all of the constants are represented by letters. Arguably any mathematical formula expressing an actual relationship between its variables is a literal equation. Take the Pythagorean theorem formula as an example. null It consists of three variables, a and b are the…

## Solve Equations Containing Fractions

Depending on the number of terms in the equation, these questions can go from being simple to extremely difficult. Easiest of these types is when you have a single term on the left side and a single term on the right. This of course was discussed earlier in this unit…

## Multiply and Divide Algebraic Fractions

A key component to multiplying and dividing algebraic fractions is knowing how to do it to ordinary fractions. That being said, you’re first expected to review how it’s done before continuing. If after a few examples you feel confident enough, you may skip it. Multiplying Algebraic Fractions Just as you…

## Add and Subtract Algebraic Fractions

Fractions always have a tendency to scare math student no matter what level of study they’re in. You’re likely to have been first introduced to fractions in elementary school, so before we start mixing in variables into our questions – as you’d expect with algebraic expressions – a good place to…

## Solving Second Degree Equations by the Quadratics Formula

A second-degree equation (also known as a quadratic equation) is one whose highest-degree term is of second degree. Generally, the highest degree in any equation dictates the maximum possible number of solutions. Thus a quadratic equation, being of degree 2, has up to two solutions or roots. This is the same reason why…

## Solve First Degree (Linear) Equations

A first-degree equation is one whose unknown variable is raised to a power of one. Another word for any first-degree equation is a linear equation because when graphed using a table of values, a straight line is generated. Generally, to solve an equations means to find a value for the…
