## Factoring Polynomials

Factoring polynomials is extremely important in your growth as a mathematician, but why? When we factor polynomials, we are finding the zeros of the function – meaning we are finding the places where the graph of the function crosses the x-axis.

## Systems of Linear Equations

Systems of Linear Equations is a common problem you will see in algebra courses, even up to the college level. You are usually given two linear equations and must find their intersection to solve the system. I find that students don’t often struggle with these problems until they are in the form of a word…

## Verbal Problems Solving for two unknowns with two equations

This Tutorial I wrote presents six problems with increasing difficulty that use Substitution and Elimination methods to obtain both unknowns. I will break it up into two parts.

## EXPONENTS

This tutorial will not give the solution to a specific problem. Rather it will show how we define the definition of a number raised to the zero power, a fractional power or a negative power.

## A Complicated Logarithm Problem

I hope you know that the following theorems are true We are going to use all of these theorems to simplify a complicated logarithm expression

## What is a Logarithm

For every function there is an inverse function. If y can be written as an expression of x, then, inversely, x can be written as an expression of y. For example, say you know that . Then… An exponential, like all functions, has an inverse. That inverse is called a logarithm. So…

## Completing the square

Completing the square is a technique that changes the form in order to easily find the maximum or minimum of the quadratic expression.

## Mathematical Induction

Mathematical induction is a form of proof that takes place in two parts. It is surprisingly useful. Part 1) Prove that the statement is true for the number 1. Part 2) Prove that if it is true for any number n then it is also true for the number n+1. Think about it… we first…

## Square Roots of Complex Numbers

Just like for real numbers there will be two square roots for a complex number. Finding these roots involves solving a system of two equations in two unknowns Let’s say we want the square root of . The square root will be of the form Then $(a+bi)^2 = a^2 +…
