Sorry it was:

√2x/9.81= √(300+x)^2+60^2/150
I'll go out on a limb here and assume you meant

(√2x)/9.81= √((300+x)^2+60^2)/150
square both sides and you have (roughly)

4x/96 = (x^2+600x+93600)/22500
2x^2-675x+187200 = 0
that has no real roots.

So, if I got it wrong, fix it and solve using the same method. Here's how wolframalpha worked it.

If I got the syntax wrong, adjust the input and see the new solution.
