Автор ответа: Аноним

X^2 - 4X + 3X - 6 = 0
X^2 - X - 6 = 0
D = 1 + 24 = 25
√ D = 5
X1 = ( 1 + 5 ) : 2 = 3
X2 = ( 1 - 5 ) : 2 = - 2

Автор ответа: logik444

x^2-4x=-3x+6
x^2-x-6=0
D=1+24=5^2
x1=(1+5)\2 = 3
x2=(1-5)\2= -2

eva301102: X^2 - 4X + 3X - 6 = 0
X^2 - X - 6 = 0
D = 1 + 24 = 25
√ D = 5
X1 = ( 1 + 5 ) : 2 = 3
X2 = ( 1 - 5 ) : 2 = - 2
