#-9/2x+1/2x^3#

When solving equations, the order of operations go like this:
1st - Multiplication or division
2nd - Addition or subtraction

Generally, these +,-,x,#div# are done from left to right.

Do the multiplication of terms first.

#1/2x * x * x = 1/2x^3#

Then, do the subtraction of like terms.

#3/4x-5 1/4x = -9/2x#

Putting them together,
#-9/2x+1/2x^3#
