Question

solve the inequality
(2x+15)/x < x

Answer 1

where did u get x^3?

Answer 2

2x+15x<x*2
x*2 -17x >0
x(x-17) >0

Answer 3

2x+15<x^2 <=> x^2-2x-15>0 D=4+60=64
x1=6 x2=-2

Answer 4

I am not sure,sorry If I wrong.

Answer 5

thx for all ur help y'alls

Answer 6

my mistake, I typed it in wrong.

15/x+2<x

Answer 7

Do you want me yo continue or you are okay?

Answer 8

here is your answer...

Answer 9

when x>17

Answer 10

so i did (2x+15) < x^2

Answer 11

@jhonyy9 where did you find the 15x ?

Answer 12

Hi Alexix,

The procedure is right. But there is a small mistake in the first step.
The inequality, gives two possible answers based on the sign of x.
\[(2x+15)/x<x\]

The work given by you is correct for x>0.

But for x<0, you get another solution
which is

\[(2x+15)/x<x\Rightarrow 2x+15>x^2\]
