Not what you're looking for?
Look at the graph above and comment on the sign of D or the discriminant. Form the quadratic equation based on the information provided and find its solution.
(-1,0) (-0.16,-2) (0.67,0) use y=ax^2+ b+c also
But if we know the roots x1 and x2 of a quadratic equation, we can write the equation in a completely equivalent form as
(x - x1)(x - x2) = 0
