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.
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
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
