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
