<h3>How to factorize a quadratic polynomial with single variable?</h3>
Quadratic polynomial with single variables are expressible in the form
where x is the variable and a,b,c are constants.
Its factored form is
<h3>Using the above method and finding the simplified form of the given expression</h3>
The given expression is
Factorizing using the aforesaid method, as we have got
a = 1, b = 3, c = 2,
thus, we have
Thus, the given sum is
Thus, the numerator of the simplified sum is
