Adding fractions that are in rational expression form? Do they have a common denominator? No? Well, then the least common denominator needs to be found. How is the least common denominator of rational expression found? Watch this video...

Use a table to find the solution set for an equation. Watch an instructor as she directs how to create ordered pairs using a given domain and check your answers using one of these ordered pairs. A practical video for anyone, student or...

Short and simple. X equals negative b divided by two(a) is the formula used to find the axis of symmetry. If the quadratic equation is in standard form, identify the values for a, b, and c and plug the values into the formula. Do the...
