... Solution of Cubic Equations Because the discriminant of the quadratic x2 + 1 is negative, we don’t get any real solutions from x2 + 1 = 0, so the only real solution is x = 1. Possible Outcomes When Solving a Cubic Equation If you consider all the cases, there are three possible outcomes when solvin ...

... If there is no constant term (c = 0) then factor out the common x and use the zero-product property to solve (set each factor = 0) If a, b and c are non-zero, see if you can factor and use the zeroproduct property to solve If it doesn't factor or is hard to factor, use the quadratic formula to solve ...

... You can get a Cube Number by multiplying any whole number (integer) by itself and then by itself again. So: The first cube number is 1, because 1 x 1 x 1 = 1. The second cube number is 8, because 2 x 2 x 2 = 8, and so on… The first ten square numbers are: 1, 8, 27, 64, 125, 216, 343, 512, 729, 1000 ...
