Using V = lwh , find an expression in factored form for the volume of this prism. Explain the general steps you used to arrive at this answer.

Question illustration
Answer:

Factor each rational dimension, write 2x − 5 as (2x − 5)/1, and multiply the three dimensions. Cancel the common factors x − 1 and 4x + 1. The volume in factored form is (x)(6x)(2x − 5), or 6x²(2x − 5).

A
Write 2x – 5 over 1.
B
Factor numerators and denominators, when possible
C
Divide out common factors to simplify.
D
