Standard form --- y= a x^{2} + bx + c = 0
 where in a  \neq 0

2 x^{2} + 2x + 2 = 0

3 x^{2} + 5x + 4 = 0

7 x^{2} + 13 x + 3 = 0

Quadratic Equation
      - an equation that can be written as ax² + bx + c=0 where a,b, and c are real numbers.

examples:
1. 3x - 2x²=7
  -2x² + 3x - 7=0

2. 2x(x-3)=15
  2x²-6x-15=0

3. (s + 3)²=1
     s² + 3²=1

Hope it help .. :)

this is the equation : ax²+bx+c
example ; (2x=5)(x-1)
2x² -2x+5x-5=-6
2x²+3x-5=-6+6
2x²+3x-5+6=0
2x²+3x+1=0

A=2,B=3,C=1
