Solve for x:
3x^3 + 2x^2 + 75x - 50 = 0
The Attempt at a Solution
I have tried substituting multiple values for "x" so that we get a factor, f(x)=0
I cannot seem to find an "x" value that will make this function=0. Is there a way to factor this function or did the book have an error when printing the equation?
