To determine
The value of the expression 2x(2x1)3x(2x+5) by indicated operation.

Explanation

Given:

The expression is 2x(2x1)3x(2x+5) .

Calculation:

Least common denominator of (2x1) and (2x+5) is (2x1)(2x+5) . Use least common denominator to simplify the expression,

2x(2x1)3x(2x+5)=(2x+5)2x(2x1)3x(2x1)(2x+5)=4x2+10x6x2+3x(2x1)(2x+5)
