3x2-30x+78 = 0
After you are done, you can click this button to see the solution, to check if you got it right.

Quick Answer
Actual Graph of y = 3 x2-30 x+78
x = no real solutions (sometimes solutions may be close approximations of the actual solutions)
Expression factored: 3 x2-30 x+78 = Expression cannot be factored






Solution ExplainedEquation:
a = 3 b = -30c = 78
Discriminant: b2-4ac = 30 2-4*3*78 = -36
Discriminant (-36) is less than zero. No solutions are defined.
