I solved the equation below and got an answer of 9+sqrt(57) but i don;t belive this is correct. help please.
5sqrt(8x+1)=x
8x+1=x^210x+25
0=x^210x+258x1
0=x^218x+24
then i completed the sqare
got 9+sqrt(57)
THANKS SO MUCH

I need to simply this equation, but I got stuck. h/(4sqrt(16+h)) = y First, I multiplied (4+sqrt(16+h)/(4+sqrt(16+h) to both sides, and I ended up with h(4+sqrt(16+h)/h. Is this correct?

i am really trying is this correct. solve: 5(x2)^2 = 3 MY ANSWER THAT I GOT IS: X = 2 + (SQRT (3) )/(5) no. 5(x2)^2 = 3 (x2)^2 = 3/5 x2 = + sqrt (3/5) x= 2 + sqrt (3/5) so the whole fraction of 3/5 is inside the sqrt yes
