Thread: anyone could help with this simple question

1/2x +1/4-1/6 these are fractions just dont know what to do with the 2x


and
multiplication

(x+5)(x+3)
x^2 +8x+15
is that correct? if not can you help, or link a site that can.
Thank you.

factorising
X^2-x-6 is this correct (x-3)(x+2)

X^2-x-6 is this correct (x-3)(x+2) Correct

Hope this helps!

ok you can subtract 1/6 from 1/4 by finding the common demnomater which is 12. so you will get 3/12 - 2/12 = 1/12
you cannot touch the 1/2x because of the x so the answer is:
1/2x + 1/12

Thank you. yes you are right

Yes you can...the common denominator in this case would be

So you would get
