You can put this solution on YOUR website! Solve the equation 3x^3 +19x^2 +13x-35=0 given that -7/3 is a zero of f(X) = 3x^3+19^2+13x-35
-------------------------
-7/3).....3.....19.....13.....-35
..........3.....12....-15....|..0
--------
Quotient:: 3x^2 + 12x - 15
Solve 3x^2 + 12x - 15 = 0
x^2 + 4x - 5 = 0
Factor::
(x+5)(x-1) = 0
x = -5 or x = 1
