x^2-10+16=0

解答

x^{2} - 10 + 16 = 0

解答

x = 6 i, x = - 6 i

求解步骤

x^{2} - 10 + 16 = 0

将

10

到右边

x^{2} + 16 = 10

将

16

到右边

x^{2} = - 6

对于

x^{2} = f (a)

解为

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

x = - 6, x = - - 6

- 6 = 6 i

- - 6 = - 6 i

x = 6 i, x = - 6 i

x^{2} - x + 0.21 = 0

3 X^{2} - 1 = 0

solvefor y,f=13-x^3-y^2-z^2-12xy-2z

so l v e f or y, f = 13 - x^{3} - y^{2} - z^{2} - 12 x y - 2 z

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

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

(3x+3)(x-1)=x(x+1)

(3 x + 3) (x - 1) = x (x + 1)
