Quadratic Equation
An equation of second degree is called a quadratic equation. It is of the form
:- ax2 + bx + c =0
The roots of a quadratic equation are
X = -b ±(b2 + 4ac)1/2 / 2a
Binomial Theorem
If n is any integer, positive or negative or a fraction and x is any real number, then
( 1+x)n = 1 + nx + n(n-1)x2 + .. . / Ị2
If IxI <<1 , then (1+x)n = 1+ nx.
