16-x^2= 32/3

解答

16 - x^{2} = \frac{32}{3}

解答

x = \frac{4}{3}, x = - \frac{4}{3}

+1

十进制

x = 2.30940 \dots, x = - 2.30940 \dots

求解步骤

16 - x^{2} = \frac{32}{3}

将

16

到右边

- x^{2} = \frac{32}{3} - 16

化简

\frac{32}{3} - 16 : - \frac{16}{3}

- x^{2} = - \frac{16}{3}

两边除以

- 1

x^{2} = \frac{16}{3}

对于

x^{2} = f (a)

解为

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

x = \frac{16}{3}, x = - \frac{16}{3}

\frac{16}{3} = \frac{4}{3}

- \frac{16}{3} = - \frac{4}{3}

x = \frac{4}{3}, x = - \frac{4}{3}
