Question

I need some steps to understand second degree equation

Answer 1

Solving Quadratic Equations

Terminology

1. A Quadratic equations is an equation that contains a second-degree term and no term of a higher degree.

2. The standard form of a quadratic equation is , where a, b & c are real numbers and .

 

Steps for Solving Quadratic Equations by Factoring

1. Write the equation in standard form:

2. Factor completely.

3. Apply the Zero Product Rule , by setting each factor containing a variable to zero.  If ab = 0, then a = 0 or b = 0.                                     

4. Solve the linear equations in step 3.

5. Check.

Note: Most quadratic equations have 2 solutions . The 2 solutions correspond to  the x-intercepts of the graph of a quadratic function.
