Explanation of Solution

Given information:

Perform the indicated operations and simplify.

  (2x+1)(3x2)5(4x1)

Calculation:

Consider the given expression.

  (2x+1)(3x2)5(4x1)

Apply method, (a+b)(c+d)=ac+ad+bc+bd

  (2x×3x+2x×2+3x2)20x+5(6x24x+3x2)20x+5=6x2x220x+5=6x221x+3=3(2x27x+1)

Hence, the resultant is 3(2x27x+1)
