Best ResponseYou've already chosen the best response.1\[x+\sqrt{x}=1\] \[\sqrt{x}=1x\]x^23x+1=0 \[x=12x+x^2\] \[x^23x+1=0\] \[x=\frac{3\sqrt{5}}{2}\] and \[1=(x+\sqrt{x})^2=x^2+2x\sqrt{x}+x\]so \[x^2+2\sqrt{x}=1\frac{3\sqrt{5}}{2}=\frac{23+\sqrt{5}}{2}=\frac{1+\sqrt{5}}{2}\]

Best ResponseYou've already chosen the best response.1\[\sqrt{x}=1x\] square both sides get \[x=(1x)^2=12x+x^2\] set equal to zero to solve the quadratic get \[x^23x+1=0\] unless i goofed up
