9x^2 -c =d

add c to each side

9x^2 = c+d

divide by 9

x^2=(c+d)/9

take the square root on each side

x = +- sqrt ((c+d)/9)

simplify

x = +- 1/3 sqrt (c+d)

Answer: 1/3 sqrt (c+d), - 1/3 sqrt (c+d)

To solve for x, you must get it alone.
Lets move c to the other side

9x^2 = c + d

Now lets divide by 9

X^2 = (c + d) / 9

Reverse x squared by finding the square root of the other side

X = square root of (c + d) / 9
