0.006q^2+50=60

解答

0.006 q^{2} + 50 = 60

解答

q = \frac{50 2}{3}, q = - \frac{50 2}{3}

+1

十进制

q = 40.82482 \dots, q = - 40.82482 \dots

求解步骤

0.006 q^{2} + 50 = 60

将

50

到右边

0.006 q^{2} = 10

在两边乘以

1000

6 q^{2} = 10000

两边除以

6

q^{2} = \frac{5000}{3}

对于

x^{2} = f (a)

解为

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

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

\frac{5000}{3} = \frac{50 2}{3}

- \frac{5000}{3} = - \frac{50 2}{3}

q = \frac{50 2}{3}, q = - \frac{50 2}{3}
