Question

can someone help me solve this?
x-1/x+2(greater than or equal to)-2

Answer 1

Answer 2

Multiply both sides by x+2 . Then move all the x's to the left side and numbers to the right ,
just like there was an = sign.

Answer 3

I got x (greater than or equal to) -2x-3

Answer 4

Move all of the x's to the left side.....

Answer 5

do I divide x from the right side away from -2?

Answer 6

theres no x in the 3, so that doesn't quite work. But you can add things to both sides....

Answer 7

x (greater than or equal to) -1?

Answer 8

So now to test it, pick a number greater than -1, like 0, and put it back in the original
inequality. Does it work?

Answer 9

You also can't forget any values where the original inequality is undefined.

Remember that the denominator of the original fraction cannot be equal to zero. So which x value makes the denom. zero?

Answer 10

So you have x = -1, and x = ? (from above)

Use those two values, draw a number line, and do point-tests to see where the inequality is true.

Answer 11

It does work so it's true

Answer 12

But we have to draw it on a number line, so shouldn't there be another solution?

Answer 13

See my last two posts.

Answer 14

Ohhhh -2 makes it zero

Answer 15

Thanks guys!

Answer 16

Did you get both of the solutions correctly?
