(x^2 /(x+1))+(√x)=1  (x^2 /(x+1))=1−(√x)  x^2 =(x+1)(1−(√x))  x^2 (1+(√x))=(1+x)(1−x)  2x^2 +x^2 (√x)=1.  x≈((−1+(√5))/2).

$$\frac{{x}^{\mathrm{2}} }{{x}+\mathrm{1}}+\sqrt{{x}}=\mathrm{1} \\ $$$$\frac{{x}^{\mathrm{2}} }{{x}+\mathrm{1}}=\mathrm{1}−\sqrt{{x}} \\ $$$${x}^{\mathrm{2}} =\left({x}+\mathrm{1}\right)\left(\mathrm{1}−\sqrt{{x}}\right) \\ $$$${x}^{\mathrm{2}} \left(\mathrm{1}+\sqrt{{x}}\right)=\left(\mathrm{1}+{x}\right)\left(\mathrm{1}−{x}\right) \\ $$$$\mathrm{2}{x}^{\mathrm{2}} +{x}^{\mathrm{2}} \sqrt{{x}}=\mathrm{1}. \\ $$$${x}\approx\frac{−\mathrm{1}+\sqrt{\mathrm{5}}}{\mathrm{2}}. \\ $$
