Factor out the X^2.
X^2(15X^2 - 115X +150) = 0
Use quadratic for that in parenthesis. Does not look pretty, but you have 1 zero. X^2 = 0
X = 0
-b +/- sqrt(b^2-4ac)/2a
a = 15
b = - 115
c = 150
-(-115) +/- sqrt[(-115)^2 - 4(15)(150)]/2(15)
115 +/- sqrt(4225)/30
[115 +/- 65]/30
X = 0
X = 6
X = 50/30 = 5/3
Lucky that the number under the radical was so clean
