If you can't factorise, you can always solve it using the quadratic equation. However, in this case, itcanbe factorised:

2.) (3w/2 - 5/4w)^3

Im clueless with this one i tried making the same common denominator, didnt help one bit, please provide explanation and full answers please

=

= = 0 for x intercepts.

But is an asyptote

Therefore

Now that you know the x intercepts, plot a few points, and find the limits.
