Question

4+5X>6x to the power 2

Answer 1

Rearranging the inequality makes the problem more recognizable:

4+5X>6x to the power 2
=> 6x²-5x-4 < 0
=> (3x-4)(2x+1) < 0

The graph is a parabola which is cut by the x-axis at x=-1/2 and x=4/3.

From the information, find out which interval of the parabola is below the x-axis.
