Quadratic Equations refer to the
equations which have a degree of 2 
E x a m p l e s :
2x² + 3x + 1 = 0
x² + 7 = 0
5x² = 0
For the above equations given in x, the highest
power(degree) is 2; Hence, making them Q u a d r a t i c
E q u a t i o n s

Representing Area of rectangle
=Length × Breadth
=(2x+1) × x 
=2x² + x 
? 2x² + x = 300
Given area equals 300
