what is the product of x2-1/x+1 and x+3/3x-3?
cross multipy x2-1 with 3x-3 and x+1 with x+3 and then reduce.
Cross multiplication would be correct if the fractions were given as being equal.
To multiply fractions, you multiply the top numbers (numerators) and put the product as the new numerator, and multiply the bottom numbers (denominators) and put the product as the new denominator.
For example: 3/4 times 5/8 would be 15/32.
