is this correct:
solve:
5(x2)^2=3
My answer:
(10 +/ sqrt 15)/(5)
looks like you expanded, then used the formula and you got the right answer properly reduced.
I think you are getting this!!!
I don't want to confuse you but I would have done the following:
(x2)^2 = 3/5
x2 = +/ sqrt(3)/sqrt(5)
x = 2 +/ sqrt(3/5)
test it with a calculator, you'll get the same decimal answer.
so my answer should like your or mine?

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
