X^2 - 4x - 10 = 0
x^2 - 4x = 10
x^2 - 4x + 4 = 10 + 4
(x - 2)^2 = 14
x - 2 = (+-) sqrt 14
x = 2 (+-) sqrt 14

x = 2 + sqrt 14 and x = 2 - sqrt 14 <== ur solutions

Hello there! The missing y-values are 12, 14, and 16.

Given all our x-values and two additional y-values, we can see that multiplying the x-value by 2 gives us the y-value. This is shown when x is 5 and 9, because multiplying 5 by 2 gave us 10, and multiplying 9 by 2 gave us 18. Because of this rule, we can multiply each given x-value by 2 to receive our y-value. Once solving, we also notice that the y-values all add by 2 to get the next factor as the data number increases. Hope this helps!
