15X^2 < 14x + 1

**Reiny**, Friday, October 19, 2007 at 7:43pmThis is an inequation, not an equation.

take everything to one side

15x^2 - 14x - 1 < 0, it factors

(15x+1)(x-1) < 0

If this**had been the equation**

y = (15x+1)(x-1) it would have been a parabola opening upwards with x-intercepts of -1/15 and 1

Between those two values the graph would have been below the x-axis

so the solution set is -1/5 < x < 1
