Solve the inequality.
Show all work
2x^2+5x<3

  • Math -

    2x^2 + 5x - 3 < 0
    (2x-1)(x+3) < 0

    If a product is negative, one factor must be negative, the other positive. So, either

    2x-1 > 0 and x+3 < 0
    or
    2x-1 < 0 and x+3 > 0

    -3 < x < 1/2

    Graph the function and you'll see this is the case
