About Algebra Quadratic Equation
- Algebra Quadratic equation is an equation that contains second-degree term and no higher degree
- Standard form is listed below. In standard form - a, b, c are real numbers. These numbers cannot be zero.
Two easiest way to solve Algebra Quadratic equations
- Factorization Ex.

- all real numbers
- The graph of which the following has the vertex of (4,-3)
- F ( x ) = x 2 - 8 x + 13
- F ( x ) = x2 − 8 x + 19
- F ( x ) = x2 + 8 x + 13
- F ( x ) = x2 + 8 x + 19
