Make a the subject of the formula

2(3√a -c)=5c^2 +1

I got a=√((5c^2 +2c+1)/6)

Yeah thats right. It doesn't say to simplify tho does it? Cos if so the quadratic being devided by the 6 needs to be solved.

I got that a = ((5c^2+2c+1)/6)^2
Because in question its √a so need to square to get a on its own
