Best ResponseYou've already chosen the best response.1\[\huge~\rm~~x=\frac{ 13~\pm \sqrt{169~x~1} }{ 4}\] \[\huge~\rm~~x=\frac{ 13~\pm \sqrt{169} }{ 4}\] Whats the square root of 169?

Best ResponseYou've already chosen the best response.1\[\huge~\rm~~x=\frac{ 13~\pm~13 \sqrt{1} }{ 4}\] now set up two equations and solve \[\huge~\rm~~x=\frac{ 13~+~13 \sqrt{1} }{ 4}\] \[\huge~\rm~~x=\frac{ 13~~13 \sqrt{1} }{ 4}\]

Best ResponseYou've already chosen the best response.1You would subtract the 4 \[\huge~\rm~6x^2+2x4=0\] and go from that
