  1. You can rewrite your inequality as
    11x^2 + 8x + 32 <0
    The minimum of the term on the left occurs at x=-4/11, and it is positive there. Therefore it has no solutions

    There are two solutions to | 16x - 5 | = 3. The greatest solution is ___. Since the expression, 16x - 5, can be either positive or negative, solve for both. 16x - 5 = 3 16x = 8 x = .5 -(16x - 5) = 3 -16x + 5 = 3 -16x = -2 x = 1/8
