It's just what the title says. We use opposite operations on one side to eliminate values that are with the variable and perform the same operations to the other side of the equals sign to keep…

This discusses what rationals and irratioinals are, then goes on to demonstrate how to eliminate any radical number in the denominator.

|
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…

This describes what to look for when simplifying radicals.

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.
