polynomials: (1/2xsquared - 3/2x+2) - (3/2xsquared+1/2x-2)

[*greenfreak*]

hey i kinda need help on my algebra. ive been having quite a few problems with the subject for quite a while now.

now on this problem

(1/2xsquared - 3/2x+2) - (3/2xsquared+1/2x-2)

so wat i did was collect the like terms

1/2xsquared+1/2x + 3/2x+3/2xsquared

which i got x2 + 1x

did i do my steps correctly???? [/tex]

Sorry, you seem a little confused.

For the x^2-term you have 1/2 - 3/2 = -1

For the x-term you have -3/2 - 1/2 = -2

For the constant term you have +2 + 2 = 4

Note: Please try to use better notation. Think about why 1/2x^2 is not the same as (1/2)x^2 or why 3/2x is not the same as (3/2)x.
