x = -2/3,7/6
x2 - 14 = 51 so x2 = 65 and then x = +/- sqrt(65) = +/- 8.06
14 minus -3 is 17
With the help of the quadratic equation formula
14 squared = 196, so you're looking for the sqrt of double that, ie 392, which is almost exactly 19.8
-14
4(h2 - 14)
-14
14
6
Negative 14
14 multiplied by 14 (or 14 squared) equals 196.
The answer is 8/36 minus 3/14 equals 1/126
