Quadratic Equation
Quadratic Equation A quadratic equation i n the variable X is an equation of the form where a,b and c are real numbers, a≠ 0 2x 2 +2x+5=0 is an quadratic equation, similarly 6x 2 +x+2=0 , and 4x 2 -5x+2=0 are also quadratic equation. Any equation in the form of p(x)=0 is a polynomial of degree 2, is a quadratic equation. but when we write the terms of p(x) in descending order of their degree, then we get the standard form of the equation. That is, ax 2 +bx+c=0, a≠0, is called the standard form of quadratic equation. Example:- (x-2) 2 +1=2x-3 Solution :- L.H.S=(x-2) 2 +1=x 2 -4x+4+1 ...
