Question

Lowest common denominator help pleaseee


3 / (x-2) - 2x/(x-2)^2

Answer 1

lowest common denominator is
\[(x-2)^2\]

Answer 2

so if you want
\[\frac{3}{x-2}-\frac{2x}{(x-2)^2}\] write
\[\frac{3(x-2)-2x}{(x-2)^2}\] and then simplify the numerator

Answer 3

so you just switched the signs around for (x-2) ^2

Answer 4

no i didn't switch the signs.
if i want the lowest common denominator for 3 and 9 i take 9
if i want it for 5 and 25 use 25 and for 7 and 49 it is 49
in other words the lcm of x and x^2 is x^2 and likewise the lcm of (x-2) and (x-2)^2 is (x-2)^2

Answer 5

I wrote the question wrong, sorry. it was supposed to be 3 / (x-2) - 2x/(2-x)^2
