a. [tex]x_{1}=0 \\x_{2}=2[/tex]
б. [tex]x_{1} =-3\\x_{2} =0[/tex]
в. [tex]x_{1}= -0,6\\x_{2} =0[/tex]
Объяснение:
a. [tex]x^{2} -2x = 0\\x(x-2)=0\\x_{1} =0\\x-2=0\\x_{2} =0+2=2[/tex]
б. [tex]3x + x^{2} = 0\\x(3+x)=0\\x_{2} =0\\3+x=0\\x=0-3\\x_{1} =-3[/tex]
в. [tex]5x^{2} + 3x = 0\\x(5x+3)=0\\x_{2} =0\\5x+3=0\\5x=0-3=-3\\x_{1} =-3:5=-0,6[/tex]
