Question

help i dont understand

Answer 1

\[\frac{ -6x }{ x-6 }-\frac{ 9 }{ x-6 }\]

Answer 2

what you don't understand?

Answer 3

Denominators are already the same. Add them up!

Answer 4

i dont understand the whole thing it says i have to add or subtract

Answer 5

so just do it:
\[\frac{-6x-9}{x-6}=-3\frac{2x+3}{x-6}\]

Answer 6

would it be \[\frac{ -6x-9 }{ x-6 }\]

Answer 7

yeah

Answer 8

yes

Answer 9

ok good thats what i got thanks

Answer 10

could you help with least common denominators

Answer 11

here it is find pair of LCD \[\frac{ 4 }{ 10x^4y^3 },\frac{ 4 }{ 6x^2y^4 }\]

Answer 12

find LCD(10,6) first
later pick maximum values of x and y powers

Answer 13

i dont know if it is right but i got 60x^4y^4

Answer 14

right

Answer 15

ohh haha ok cause usually when it goes so right then im wrong lol thanks for your help :)

Answer 16

yw

Answer 17

lcd(10,6) = 30

Answer 18

does that mean it 30 x4 y4

Answer 19

Seek a Prime Factorization.

10 = 2*5
6 = 2*3

lcd = 2*3*5 -- Do you see why?
