    Arrow [SOLVED] inequalities

    the product of twon numbers is less than 340. one of the numbers is 3 less than the other. what are the possible values of the larger number?

    this is my interpretation
    1=> x
    2=> x-3
    P=> x(x-3)< 340

    x(-3)<340
    x^2-3x<340
    x^2-3x-340<0

    there are no factors. so I need to use the quadratic formula??

    did you make a typo where my red edit is

    Your working is correct and I'd use the quadratic formula to solve for x.
