Solve Absolute value inequation.

The absolute value has two parts so like |x| can be written as x for x>=0 and -x for x

Introduction to Complex Numbers

Consider the equation x^2=-1. Since squaring any number is 0 or larger, no real number will make this equation true. Create a number i such that i^2=-1. By “adding” i to the real numbers, the complex numbers (having the form a+bi where a and b are real numbers) are created. Visually represent a point a+bi…

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…

Part 2 Verbal Problems Systems of Equations

This is the second part with problems 4-6.

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 log_ab^c=c*log_ab log_ax + log_ay = log_a(x*y) log_ax - log_ay = log_a(x/y) 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 y=2*x. Then… x = \frac{y}{2}} 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.
