can some one help me on how i work these qustions out..i need to simplify and write out the full solutions.

2x + 4 / 2

and

2x^2 / x^3

I'm not sure what you mean by write out the full solutions but If that means find x...

the first one is simplified and solved as

2x+4/2= 2x+2 (simplified)

2x+2=0

2x=-2

x=-1

for the 2nd one simplified is

2x^2/x^3 subtract the higher exponent x from the lower exponent x and thus...

2/x

actually simplified the first one should be 2x+4/2= x+1 since you can cancel out the 2's

2x + 4 / 2

= x + 2

2x^2 / x^3

= 2/x
