It looks like a quadratic equation, so move everything to one side using inverse operations and factor.

you probably want to start with \[x^2-6x=-3\] and then complete the square otherwise start with \[x^2-6x+3=0\] and use the quadratic formula because \(6\) is even, completing the square is probably easiest do you know how to do that?

Or complete the square.....

if you use the quadratic formula then a=1 b= -6 c= 3

you need to get x by its self so minus it from both sides and you get -4x=-3 and divide both sides to get x by itsself so you answer is x=1

hope i helped:)

actually 1 is not the answer

oh wait yeah sorry i messed up

if you start with \[x^2-6x=-3\] then take half of 6, which is 3, square it to get 9 and then write \[(x-3)^2=-3+9=6\] take the square root, don't forget the \(\pm\) and get \[x-3=\pm\sqrt6\] then add 3 to both sides and you are done

I had gotten stuck on this part x^2 - 6x +3 = 0

Quadratic formula is: x = [-b +-sqroot(b² - 4*a*c)] / 2a

  • anonymous
I got x = 10.9 or x = -1.1 is it wrong?
anonymous
  • anonymous
\[x=3\pm\sqrt6\] is the correct answer
anonymous
  • anonymous
yeah satellite73 is correct I messed up

@jbarreto17 Do not estimate the square root unless the question specifically asks you to.
