## Answers ( )

Take the divisors and dividends in separate brackets as it would not affect the equation in this case.

Therefore,

[(2x-3)÷(x+1)][(2x+3)÷(x+1)]

Therefore by multiplying we get,

(2x-3)(2x+3)÷(x+1)²

We know that,

(a+b)²=a²+2ab+b²

(a+b)(a-b)=a²-b²

Therefore,

By using the above identities in the equation we get,

4x²-9÷x²+2x+1

Multiplying the equation by x²/x²

(4x²+2x+1)x²/x² – 9/x²

(4x²+2x+1)x²-9/x²

4x²+2x+1-9/x² is the answer.
