NO REAL SOLUTIONS but rather complex solutions:

x = -13i, 13ix=13i,13i

Explanation:

Isolate the x^2x2 by subtracting 169 from both sides...

x^2+cancel(169-169)=0-169 -> x^2 = -169

Now take the square root of both sides to the x

sqrt(x^2)= sqrt(-169) -> x= +- sqrt(-169)

Note: there are NO REAL SOLUTIONS! but rather two complex solutions denoted by the symbol i

So x = -13i, 13i
