Demonstrates how to solve for a variable under the radical that needs to isolated first after entering the given value for the other variable in a formula.

Demonstrations that emphasize the fact that a fraction bar acts like parentheses in that the each part of the fraction must be factored so that there is a product of factors on both top and bottomof…

Another equation with fractions that we eliminate first by multiplying through by the LCD (least common denominator), and after that the rest is live others we've explained.
