About Algebra Quadratic Equation

  1. Algebra Quadratic equation is an equation that contains second-degree term and no higher degree
  2. 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

  1. Factorization
  2. Ex.
    • Write the equation in standard form x2+ 4x -5
    • Factor completely. (x+5)(x-1)
    • Apply the Zero Product Rule x+5 =0 and x-1 = 0
    • Solve the linear equations in step 3. X =-5 and x = -1
    • Check
    2. Graphic method
