The key to solving this equation is eliminating the fractions first by multiplying by the least common denominator and dividingout equal factors. Note that the integer term must be multiplied by…


Shows how to ofirst find the coordinates of the vertex, then choose other inputs to find two more points on each side of the vertex, plott them and draw the graph.


Shows how to create common bases so that then the exponents can be set equal to each other and that equation can be solved.


This video gives the formula for calculating compound interest and then demonstrates how to calculate the future amount after a given number of years.


Shows three examples of using a unit fraction as an exponent and coverting itt to its radical form sot the result can be further understood.


A brief informal reasoning of why any division can be changed to a multiplication by reciprocating the second number or fraction, i. e. the number going into the other number. Then an example of…


This is a quick example of factoring the numerator and denominator of a combined fraction where all the factors are separated in order to find those that divide to one.


This shows both a subtraction and an addition example for finding the sum and difference of two trinomials.


Two examples of expressions with negative exponents that are changed to expressions with positive exponents, leaving the numerical factor as is.


Two examples are shown with negative exponents. The reciprocal is produced first before applying the exponent to the numerator and denominator in each example.


A simplification of a fraction with products and exponents in parentheses raised to an external power


A short review of these two rules and then an application of them to two multifactor expressions.


A quick example of distributing an external exponents to all factors in a rational expression


An example of how we distribute an exponent outside of parentheses to all factors within.


A short demo of this rule
