I have these three inequalities that I am supposed to solve, I think I came up with the right answer but I'm not even 100% sure it's in the correct format.(adsbygoogle = window.adsbygoogle || []).push({});

A. 6x^2 < 6+5x

my work:

6x^2-5x-6 < 0

solutions are then 3/2 and -2/3

so the answer I got is:

-2/3 < x < 3/2

B. x^2+8x > 0

my work:

soutions I got were 0, -8

so my answer is:

-8 < x < 0

C. (x+2)(x^2-x+1) > 0

my work:

x+2 > 0 and x^2-x+1 > 0

solutions are then -.414 and 2.414

so my answer is:

-4.14 < x < 2.414
