WebFirst, the expression needs to be rewritten as 2x^{2}+ax+bx-1. To find a and b, set up a system to be solved. a=-2 b=1 . 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. sap netweaver portal epdchile.cl
