(3x^2-2)/(x^2+x+1)= 2/1

解

\frac{3 x ^{2} - 2}{x ^{2} + x + 1} = \frac{2}{1}

解

x = 1 - 5, x = 1 + 5

+1

十進法表記

x = - 1.23606 \dots, x = 3.23606 \dots

解答ステップ

\frac{3 x ^{2} - 2}{x ^{2} + x + 1} = \frac{2}{1}

3 x^{2} - 2 = (x^{2} + x + 1) \cdot 2

解く

3 x^{2} - 2 = (x^{2} + x + 1) \cdot 2 : x = 1 - 5, x = 1 + 5

x = 1 - 5, x = 1 + 5

1/(x^2)+8/x+15=0

\frac{1}{x ^{2}} + \frac{8}{x} + 15 = 0

80x-(360)/(x^2)=0

80 x - \frac{360}{x ^{2}} = 0

2/(x-2)-4/(x^2-2x)=3

\frac{2}{x - 2} - \frac{4}{x ^{2} - 2 x} = 3

2/(x+1)+3/x = 5/(x-2)

\frac{2}{x + 1} + \frac{3}{x} = \frac{5}{x - 2}

8/q+2=(q+4)/(q-1)

\frac{8}{q} + 2 = \frac{q + 4}{q - 1}
