36z^2-64=0

解答

36 z^{2} - 64 = 0

解答

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

+1

十进制

z = 1.33333 \dots, z = - 1.33333 \dots

求解步骤

36 z^{2} - 64 = 0

将

64

到右边

36 z^{2} = 64

两边除以

36

z^{2} = \frac{16}{9}

对于

x^{2} = f (a)

解为

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

z = \frac{16}{9}, z = - \frac{16}{9}

\frac{16}{9} = \frac{4}{3}

- \frac{16}{9} = - \frac{4}{3}

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

2 x (x - 4) = 5

x^{2} = 5^{2} + 1 0^{2}

12 = 4 x^{2} - 6 x + 8

x^2-sqrt(7)x-3=0

x^{2} - 7 x - 3 = 0

x^2-12x+51=2x+3x

x^{2} - 12 x + 51 = 2 x + 3 x
