The expression
Formula used:
Fractions are multiplied as
To factor a polynomial split the middle term in such a way that sum of two numbers is the middle term and product of two numbers is same is product of first and last term.
Calculation:
Consider the expression
Take the common terms from the numerator of both the terms,
Take the common terms from the denominator of both the terms,
Recall that square of difference of two numbers a and bis
Therefore,
