An urn contains 4 red, 6 green, and 2 yellow balls.  If 3 balls are randomly selected what is the probability that you pick one of each color?

do you mean add both of the equations together

because if you do the answer is 10x-5

step-by-step explanation:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
