First, left hand side needs to be rewritten as 15x^{2}+ax+bx-2. To find a and b, set up a system to be solved. 1,-30 2,-15 3,-10 5,-6 . Since ab is negative, a and b have the opposite signs. Since a+b is negative, the negative number has greater absolute value than the positive. List all such integer pairs that give product -30.
