Algebra and Equations
- How to Solve Absolute Value Equations
Solve absolute value equations by splitting into two cases, why two answers appear, when there is no solution, and how absolute value inequalities differ.
- Completing the Square, Step by Step
Learn completing the square: why the method works geometrically, how to handle a leading coefficient, and how it produces vertex form and the quadratic formula.
- How to Solve Compound Inequalities (AND and OR)
Solve compound inequalities joined by AND or OR, graph the solution on a number line, and tell which combinations give no solution or every number.
- The Quadratic Formula: How and Why It Works
Learn the quadratic formula, where it comes from, and how to use it to solve any quadratic equation, with worked examples and practice problems.
- Solving Quadratic Equations by Factoring
Solve quadratics by factoring using the zero product property, why the equation must equal zero first, and how to factor the common trinomial patterns.
