how do you write quadratic equation in standard form?give at least 3 example.



Sagot :

standard form --- y= a[tex] x^{2} [/tex] + bx + c = 0
 where in a [tex] \neq [/tex] 0

2[tex] x^{2} [/tex] + 2x + 2 = 0

3[tex] x^{2} [/tex] + 5x + 4 = 0

7[tex] x^{2} [/tex] + 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 .. :)
