Help me please solve the equations (x-3)^2+2x=0 x^4-2x^3+5x^2-2x+1=0

Question

Help me please
solve the equations
(x-3)^2+2x=0
x^4-2x^3+5x^2-2x+1=0

Answer 1

X^2-6x+9+2x=0
x^2-4x+9=0
D<0<br>x - нету корней
x^2-2x+5-2/x+1/x^2=0
x^2+1/x^2-2(x+1/x)+5=0
x+1/x=t
t^2-2-2t+5=0
t^2-2t+3=0
D<0<br>t - нету корней
x - нету корней
