Multiplying a fraction

[SammyS]

Okay, I think I have it now: (x² + 2x + 1)/(18cw³) times (12c³w)/(x²-1) = (x+1)²(12c³w)/(18cw²)(x+1)(x-1) Cancel the (x+1) = (12c³w)(x+1)/(18cw²)(x-1) Cancel the c and w = (12c²)(x+1)/(18w)(x-1) divided by 3 (numerator and denominator) = (4c²)(x+1)/(6w)(x-1) divided by 2 (numerator and denominator) = (2c²)(x+1)/(3w)(x-1) Answer

Enclose the entire denominator in parentheses.
(2c²)(x+1)/((3w)(x-1)) .

You could've reached the last step by recognizing that 6 is the GCF for the numerator and denominator.
