*Quadratic Equations*

As calculus is an integral part of Vedic mathematics, differential calculus is made use of in Vedic sutras for solving quadratic equations by breaking them into two simple equations.

Accordingly it has been stated in the Vedas that the first differential of the quadratic equation is equal to square root of the discriminant.

The discriminant is given as the square of
coefficient of 'x' minus the product of double the coefficient of x** ^{2}**
and double the independent term.

Example :

Consider x** ^{2}**
+ 4x - 3 = 0

Then its first differential is 2x + 4

Its discriminant is 4** ^{2}**
- 2 * 1 * 2 * (-3) = 28

Therefore according to the sutra

2x + 4 = **±**
(28)** ^{-2}** =

==> x = 2**
****±
(7)**^{-2}

There are some more sutras and methods which when applied to quadratic equations in special cases make the job easier. Given below are a few types (methods).
