Quadratic Equations

Quadratic Equations

1. An equation that is in the form of ax^2+bx+c=0, where a, b, and c are real numbers and a=/0.

   • Leading Coefficient is a.
     • a=1
     • a=/1

2. The graph of a quadratic equation is a parabola, when a is greater than 0.

   • When a>0, then the parabola opens upwards.
     • This is a upward opening parabola.
   • When a<0, then the parabola opens downwards.
     • This is a downward opening parabola.

3. Solutions of quadratic equations

   • Factorization Method
   • Quadratic Formula Method
   • Completing the Square Method
