Question

x(2x+1)(5x−30)≤0
PLEASE HELP

Answer 1

Answer:

Step-by-step explanation:

X<_=0

10x²-55x-30<_0

2x²-11x-6<_0

2x²-12x+x-6<_0

(2x+1)(x-6)<_0

x<_-1/2 or x<_6

Answer 2

Critical values
X=0 x=-0.5 and x=6
(The step where I expanded was unnecessary but hopefully explained. Do not divide through by x else you will lose a critical value.)
