We all know quadratic equations are those equations which have two roots or we can tell which has two values of X for which the function becomes zero.A quadratic equation is of type
ax^2+bx+c=0
Has roots in the form of given by SreeDharcharya formula
X= [-b+(b^2-4ac)^1/2]÷2a and
-b-(b^2-4ac)^1/2]÷2a.
Where (b^2-4ac) is called the discriminant, and a,b,c are constants in the above equation.
