Question #0450b

Answer 1

`(x-1)/2`

Explanation:

In algebraic fractions, check for any possible factoring first

`(3x^2-3) div (6x+6) = (3x^2-3) /(6x+6) " "larr` common factors.

=`(3(x^2 -1))/(6(x +1))" "(larr "difference of squares")/"color(white)(x)`

=`(cancel3cancel((x+1))(x-1))/(cancel6^2cancel((x+1))`

=`(x-1)/2`
