Two examples of how to deal with negative fractional exponents


Two examples of how to deal with fractional exponents on negative numbers.


Shows how these forms are interrelated


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…


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…


A quick run through the use of a^2 + b^2 = c^2 to find an unknown side of a right tirangle if we know the other two sides.


Shows how to factor the greatest common factor from a simple linear binomial
