А) (y+1)(y^2-2y-3)=0
y+1=0, y1=1,
y^2-2y-3=0
D=4+12=16=4^2
x2=(2+4)/2=3, x3=(2-4)/2=-1
b) (2y-3)(2y^2+y-1)=0
2y-3=0, 2y=3, y1=1.5
2y^2+y-1=0
D=1-4*2*(-1)=1+8=9=3^2
x2=(-1+3)/4=0.5
x3=(-1-3)/4=-1
в) (3x-2)(x-1)=4(x-1)^2
(3x-2)(x-1)-4(x-1)(x-1)=0
(x-1)(3x-2-4x+4)=0
(x-1)(2-x)=0
2x-x^2-2+x=0 *(-1)
x^2-3x+2=0
D=9-8=1
x1=(3-1)/2=1, x2=(3+1)/2=2
