SOLUTION: Please find the x-intercept to y=3x^3-14x^2+17x-6.

Question 125383: Please find the x-intercept to y=3x^3-14x^2+17x-6.
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
the coefficients add up to zero so x=1 is a zero of the polynomial.
Use synthetic division to find the other factor:
1)....3....-14....+17....-6
........3.....-11....6...|..0
Quotient: 3x^2-11x+6
---------------------------
Use the quadratic formula to find the remaining zeroes:
x = [11 +- sqrt(121-4*3*6]/6
x = [11 +- sqrt(49)]/6
x = 3 or x = 2/3 or x = 1
