4/3 p^2-1=0

解答

\frac{4}{3} p^{2} - 1 = 0

解答

p = \frac{3}{2}, p = - \frac{3}{2}

+1

十进制

p = 0.86602 \dots, p = - 0.86602 \dots

求解步骤

\frac{4}{3} p^{2} - 1 = 0

将

1

到右边

\frac{4}{3} p^{2} = 1

在两边乘以

3

4 p^{2} = 3

两边除以

4

p^{2} = \frac{3}{4}

对于

x^{2} = f (a)

解为

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

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

\frac{3}{4} = \frac{3}{2}

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

p = \frac{3}{2}, p = - \frac{3}{2}

流行的例子

3 x^{2} - 22 x + 36 = 0

t^{2} - t - 6 = - 6

0 = 4 x - x^{2} - x^{2}

20.13=-4.9t^2+15.3t+28.32

20.13 = - 4.9 t^{2} + 15.3 t + 28.32

solvefor x,f=4x^2-5f(5)

so l v e f or x, f = 4 x^{2} - 5 f (5)
