anonymous · Answer

$$\sqrt{4x+1}+1=40$$

anonymous · Answer

yes that is the problem!

anonymous · Answer

subtract 1, square both sides
$$\sqrt{4x+1}=39$$
$$4x+1=39^2=1296$$
$$4x=1295$$
$$x=\frac{1295}{4}$$ whatever that is

anonymous · Answer

oh damn i made a mistake!

anonymous · Answer

$$39^2=1521$$

anonymous · Answer

so you get 
$$4x+1=1521$$
$$4x=1520$$
$$x=380$$
