I think you meant to write 9x%5E2=14 right?


9x%5E2=14 Start with the given equation.


x%5E2=14%2F9 Divide both sides by 9.


x=sqrt%2814%2F9%29 or x=-sqrt%2814%2F9%29 Take the square root of both sides (don't forget the "plus/minus")


x=sqrt%2814%29%2Fsqrt%289%29 or x=-sqrt%2814%29%2Fsqrt%289%29 Break up the square root.


x=sqrt%2814%29%2F3 or x=-sqrt%2814%29%2F3 Take the square root of 9 to get 3


========================================================

Answer:


So the solutions are x=sqrt%2814%29%2F3 or x=-sqrt%2814%29%2F3
