Hello everyone,

Could someone please help me on this ancient mathematics problem?

Solve by the method of your choice: 1-third of a school of fish and 3 times the square root of the remaining part of the school were seen in the ocean; and in a river was seen a male fish along with 3 female fish making up the remainder of the school. How many fish were in the school?

My attempt:

I think one would have to use the quadratic equation and one would set it up like the following:

1/3x+3(square root(2/3x))+1+3=x

From here would I solve for x by using the quadratic equation?

Could someone please tell me if this is correct so far?

Thank you very much
