    -4
    Step-by-step explanation:

    To solve the problem, we divide the whole expression by 2:

    2x^2 + 10x < - 8 → x^2 + 5x < - 4

    → x^2 + 5x + 4 < 0

    Factorizing

    → (x+4) (x+1) < 0

    The expression is ONLY negative when:

    x>-4 and x<-1

    Therefore, the solution is:

    -4
