Question

when you're subtracting rationals, do you make it into a plus sign and make EVERYTHING in the numerator of the second negative, or just make 1 number negative?
for examples
x-1 4x+2
---- - -----
x(x-3) x(x-3)
would you make it into a plus sign, and then make 4x and 2 negative?
-4x-2

Answer 1

yes

Answer 2

in the other equation you did how did you get positive 2?

Answer 3

the last one you answered

Answer 4

\[\frac{x-1-(4x+2)}{x(x-3)}\]
\[\frac{x-1-4x-2}{x(x-3)}\] etc

Answer 5

well in the last one you caught me in a dumb algebra mistake that is why!

Answer 6

should be
\[\frac{x+2}{x}=\frac{x-1}{x}-\frac{4x+2}{x(x-3)}\]
\[(x+2)(x-3)=(x-1)(x+3)-4x-2\]
\[x^2-x-6 = x^2-2 x-5\]
\[-x-6=-2x-5\]
\[x=1\]

Answer 7

wait what? i get x^2-x-6=x^2-8x+1
i keep on looking it over but i can't figure it out darn it

Answer 8

oh man did i mess up again? hold on

Answer 9

ok so,
(x-3) and (x+2) equal x^2-x-6.
(x-1) and (x-3) euqlas x^2-4x+3.
then when i combine them
x^2-x-6=x^2-4x+3x-4x-2

Answer 10

ok now you have caught me in two mistakes, so i am going to quit.

you are right it is
\[(x+2)(x-3)=(x-1)(x-3)-4x-2\]

Answer 11

then i combine like terms and get x^2-x-6=x^2-8x+1

Answer 12

no please don't this is a very confusing problem lol

Answer 13

then i get 2x^1+7x+7

Answer 14

ok but i am making mistake after mistake. lets see what we get now

Answer 15

i mean 2x^2+7x+7

Answer 16

did you get
\[x^2-x-6 = x^2-8 x+1\]?

Answer 17

yes

Answer 18

ok subtract
\[x^2\] from both sides

Answer 19

let me know what you get

Answer 20

7x+7

Answer 21

what happened to your equal sign?

Answer 22

0=7x+7

Answer 23

oh wait let me do this again

Answer 24

OMFG

Answer 25

\[x^2-x-6 = x^2-8 x+1\]
\[\cancel{x^2}-x-6=\cancel{x^2}-8x+1\]
\[-x-6=-8x+1\]

Answer 26

I GOT THE RIGHT ANSWER THANK YOU!!!!!!!!!!!!!! FINALLY THIS PROBLEM IS THE WORST THANK YOU!!!!!!!!!!!!!

Answer 27

YES!!!!!!!!!

Answer 28

took forever!!!!!!!

Answer 29

x=1
