Shows how to shoose appropriatate input values to find five points, then plot them and draw the graph.
|
|
|
This includesradicals that contain variable factors, but continues the simplification of various terms in a sum or difference so that possible like terms can be added orsubtracted.
|
|
|
A subtraction of fractionso where the denominators have no factors in common so we simpllly multiply the two together to create the LCD. Then both fractions are adjusted by multiplying each…

|
|
This demonstrates adding two rational expressions that have different terms individually in the numerator and a common denominator. When the fractions are added, it creates the possibility of adding…

|
|
Two examples of expressions with negative exponents that are changed to expressions with positive exponents, leaving the numerical factor as is.
|
|
|
Shows how square rooting is the opposite of squariing
|
|
|
Demonstrates distribution when radicals are invovled.
|
|
|
A quick look at distributin a radical across a sum of a whole number and a different radical
|
|
|
A qucikc look at a simple fourth root of a combined pair of them, numbers only.
|
|
|
Multiplying two radical expressions by showing the factorization of the numbers and using even exponents to remove variable factors.
|
|
|
An example that is a little more complicated about how to simplify radicals that are being multiplied
|
|
|
Two examples of reducing radicals to then be able add or subtract like radicals
|
|
|
Here we solve a rational equation by multiplying each of the terms in the equation by the LCD of all of the fractions. This allows us to divide to one all of the factors in the denominators and the…

Shows cross multipication of two single fractions set equat to each other to create a new equation that has no fractions and is then solvable by the typical methods.
|
|
|
This applies the factoring methods learned previously to solving a quadratic equation in standard form, that is with all th eterms on the left of the equals sign and 0 on the right
