A quadratic can be written in the form . If "there is a zero at -4", then y= 0 when x= -4: . If "there is a zero at -1", then y= 0 when x= -1: . If "the y-intercept is at -8" then y= -8 when x= 0: .

That gives you three equations to solve for a, b, and c. - November 7th 2012, 05:04 AMSorobanRe: Quadratic Equation
