Two examples here of solving radical equations. Both have one radical that each need isotation before squaring both sides.. Emphasis is p laced on checking your answer because the one arrived at…

Multiplication of two radicals by pairing all numbers after prime factorization and taking half of all even exponents with variables as a base.

|
Multiplying two radical expressions by showing the factorization of the numbers and using even exponents to remove variable factors.

Single fractions set equal to each other forms a proportion. When presented with this, it can be "cross multiplied" to eliminate the fractions. The resulting equation has a term with the…

Demonstrates using factoring skills to separate and identify all of the necessary factors that make the LCD (Least common denominator) that can be used as a multiplier through a rational equation to…

|
This has two examples so that you can learn to watch out for what looks like a solution but is not because it creates division by zero if you check the answer in the original equation. The other…

Demonstrates how to reduce a complex fraction when the technique of factoring a greatest common factor (GCF) is needed.
|
|
|
A two step process is shown here. First, as always, look for a greatest common factor (GCF) and remove it from all terms. Then second, the resulting quadratic expresssion can then be factored into…

This demonstrates how some quadratic equations need to be simplified and put in standard form before the quadratic expression can be factored so the factors can be set to zero and solved.
