Concept of Quadratic Equation of Rectangle to Relation all Mathematics Method

Abstract

In this research paper, the equation of rectangle explained in the form of quadratic equation. In this research paper, the main quadratic equation of rectangle is $x^{2}-B(\square PQRS)x+A(\square PQRS)=0$, which is outcome of \lq Basic theorem of perimeter relation of square-rectangle'. If the value of \textbf{a} is not equal to 1 $(a\neq1)$, then the quadratic equation of rectangle is $ax^{2}-B(\square PQRS)x+a.A(\square PQ'R'S')=0\;\;[ax^2-bx+c=0]$ and if the value of \textbf{a} is 1 ($a=1$), then quadratic equation of rectangle is $x^{2}-B(\square PQRS)x+A(\square PQRS)=0\;\;[x^2-bx+d =0]$. In this Research Paper Three methods of quadratic equation of rectangle are explained i.e. (i) Factorization method of rectangle (ii) Completing square of method of rectangle (iii) Formula method of rectangle. We are trying to give a new concept \lq\lq Relation All Mathematics" to the world. I am sure that this concept will be helpful in Agricultural, Engineering, Mathematical world etc.
