Best ResponseYou've already chosen the best response.4Well first we have to get the c term by using (b/2)^2 \[(\frac{ 6 }{ 2 })^2=9\] So now add that to both sides: \[(x^26x+9)=8+9\] Simplify: \[(x3)^2=1\]

Best ResponseYou've already chosen the best response.4Now take the square root of both sides: \[\sqrt{(x3)^2}=\pm \sqrt{1}\] Since the square root of 1 is 1 we leave it: \[x3= \pm1\] Now add 3: \[x3+3=\pm1+3\] \[x=\pm1+3\] Separate and do then separately: \[x=1+3=4\] \[x1+3=2\] And there you go :)
