0.000006x^2-0.02x+25=75-0.02x

解答

0.000006 x^{2} - 0.02 x + 25 = 75 - 0.02 x

解答

x = \frac{5000}{3}, x = - \frac{5000}{3}

+1

十进制

x = 2886.75134 \dots, x = - 2886.75134 \dots

求解步骤

0.000006 x^{2} - 0.02 x + 25 = 75 - 0.02 x

将

25

到右边

0.000006 x^{2} - 0.02 x = - 0.02 x + 50

将

0.02 x

para o lado esquerdo

0.000006 x^{2} = 50

两边除以

0.000006

x^{2} = \frac{50}{0.000006}

对于

x^{2} = f (a)

解为

x = f (a), - f (a)

x = \frac{50}{0.000006}, x = - \frac{50}{0.000006}

\frac{50}{0.000006} = \frac{5000}{3}

- \frac{50}{0.000006} = - \frac{5000}{3}

x = \frac{5000}{3}, x = - \frac{5000}{3}
