6x^2-17=7

解答

6 x^{2} - 17 = 7

解答

x = 2, x = - 2

求解步骤

6 x^{2} - 17 = 7

将

17

到右边

6 x^{2} = 24

两边除以

6

x^{2} = 4

对于

x^{2} = f (a)

解为

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

x = 4, x = - 4

4 = 2

- 4 = - 2

x = 2, x = - 2

solvefor x,x^2+y^2+z^2-2x-4y-6z+1=0

so l v e f or x, x^{2} + y^{2} + z^{2} - 2 x - 4 y - 6 z + 1 = 0

- 3 x^{2} = 7, x + 5 = 0

2x*4x=8,x^1*x^1=8x^2

2 x \cdot 4 x = 8, x^{1} \cdot x^{1} = 8 x^{2}

c^{2} = 8.41 + 4

3x^2-2sqrt(6)+2=0

3 x^{2} - 26 + 2 = 0
