**Reiny**, Monday, June 4, 2012 at 8:43pmSince you have given me 4 distinct roots, the equation must be a quartic not a cubic

it would be

y = ax(x-2)(x+√5)(x-√5)

= ax(x-2)(x^2 - 5)

to find a, sub in your given point (2,20)

**Steve**, Tuesday, June 5, 2012 at 12:21amIf you mean roots of 0,2+√5 and 2-√5, then then

y = x^3 - 4x^2 - x
