is this correct:

solve:

5(x-2)^2=3

(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:

(x-2)^2 = 3/5
x-2 = +/- sqrt(3)/sqrt(5)
x = 2 +/- sqrt(3/5)

test it with a calculator, you'll get the same decimal answer.

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