How to solve hidden quadratics
Quadratic Equation in Standard Form: ax 2 + bx + c = 0. Quadratic Equations can be factored. Quadratic Formula: x = −b ± √ (b2 − 4ac) 2a. When the Discriminant ( b2−4ac) is: positive, there are 2 real solutions. zero, there is one real solution. negative, there are 2 complex solutions. See more The Standard Formof a Quadratic Equation looks like this: 1. a, b and c are known values. acan't be 0. 1. "x" is the variableor unknown (we don't know it yet). Here are some examples: See more Play with the "Quadratic Equation Explorer" so you can see: 1. the function's graph, and 2. the solutions (called "roots"). See more There are usually 2 solutions (as shown in this graph). And there are a few different ways to find the solutions: See more As we saw before, the Standard Formof a Quadratic Equation is But sometimes a quadratic equation does not look like that! For example: See more WebSolve the trigonometric equation. Solution. Using the definition of cotangent, we rewrite the equation in the form. Multiply both sides by and rearrange the terms: Apply now the Pythagorean trig identity to represent as. So the equation becomes. or. By changing we get the following quadratic equation: It has the roots.
