The general form of quadratic equation is ax²+bx+c=0,where a, b, c are known values, x is variable and a≠0.This equations can also occur in different forms such as ax²+bx=0, ax²+c=0 and ax²=0.

## start with values of a=o, b=0, c=0

## Start with values of b=0, c=0
## change value of a to 1 (keeping b=0, c=0 and see what happens)
+
## In quadratic equations why is a≠0? What happens to the quadratic equation, if a=0?
## change value of c to 1, 2, 3 etc  (keeping a=1, b=0 and see what happens)
+
## Change value of a to 1 (keeping b=0, c=0 and see what happens)
## change value of b to 1, 2, 3 etc  (keeping a=1, c=0 and see what happens)

## Change value of c to 1, 2, 3 etc  (keeping a=1, b=0 and see what happens)

## Change value of b to 1, 2, 3 etc  (keeping a=1, c=0 and see what happens)
 
# In each of the above cases, discuss with students the meaning of the curve plotted and how the curve changes on change in values.
