x2+x2(x+1)2=3x2+x2(x+1)2=3


x2+(xx+1)2=3x2+(xx+1)2=3


x2+(1−1x+1)2=3x2+(1−1x+1)2=3


x2+1−2x+1+(1x+1)2=3x2+1−2x+1+(1x+1)2=3


x2+2−2x+1+(1x+1)2=4x2+2−2x+1+(1x+1)2=4


x2+2x+2−2x+1+(1x+1)2=4x2+2x+2−2x+1+(1x+1)2=4


x2+2xx+1+(1x+1)2=4x2+2xx+1+(1x+1)2=4


(x+1x+1)2=4(x+1x+1)2=4


x+1x+1=±2x+1x+1=±2


x=1±5√2x=1±52, −3±i3√2
