Why write 5/10 instead of 1/2 or 0.5?

Perhaps you mean (6x^2- 3x+ 5)/10? Saying that is the same as saying which in turn is the same as . You can use the quadratic formula to determine where that polynoial is

**equal**to 0. It will be less than 0 between those two values so it is only necessary to determine how many integers there are between the two roots of . - October 29th 2013, 09:36 AMPlatoRe: Quadratic inequality
