The answer is X^2 -9 +66/x^2 +8
2 to the second power and 2 squared are the same number
they both are 2^2
A leg of a right triangle can never be greater then the hypotenuse
this formula will tell you if it's a valid right triangle
![{?}^{2} + {?}^{2} = {?}^{2}](https://tex.z-dn.net/?f=%20%7B%3F%7D%5E%7B2%7D%20%2B%20%7B%3F%7D%5E%7B2%7D%20%3D%20%7B%3F%7D%5E%7B2%7D%20)
the first two question marks are the legs of the triangle while the one after the = is the hypotenuse.
THE STEPS:
![{3}^{2} + { \sqrt{7}^{2} } = {4}^{2}](https://tex.z-dn.net/?f=%20%7B3%7D%5E%7B2%7D%20%2B%20%7B%20%5Csqrt%7B7%7D%5E%7B2%7D%20%7D%20%3D%20%7B4%7D%5E%7B2%7D%20)
![9 + {2.65}^{2} = 16](https://tex.z-dn.net/?f=9%20%2B%20%7B2.65%7D%5E%7B2%7D%20%3D%2016)
![{2.65}^{2} = 7](https://tex.z-dn.net/?f=%20%7B2.65%7D%5E%7B2%7D%20%3D%207)
![9 + 7 = 16](https://tex.z-dn.net/?f=9%20%2B%207%20%3D%2016)
