a=(x-3)^{10}+1

解答

a = (x - 3)^{10} + 1

解答

x = 10 a - 1 + 3, x = - 10 a - 1 + 3

求解步骤

a = (x - 3)^{10} + 1

交换两边

(x - 3)^{10} + 1 = a

将

1

到右边

(x - 3)^{10} = a - 1

对于

(g (x))^{n} = f (a)

，n 为偶数，解为

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

解

x - 3 = 10 a - 1 : x = 10 a - 1 + 3

解

x - 3 = - 10 a - 1 : x = - 10 a - 1 + 3

解为

x = 10 a - 1 + 3, x = - 10 a - 1 + 3

x^{3} - 3 x^{2} - 18 x = 0

x(x+1)(x+2)=63(x+1)

x (x + 1) (x + 2) = 63 (x + 1)

36 x^{3} = 144 x

x^{4} - 13 x^{2} - 48 = 0

x^3+3x^2+3x-1=0

x^{3} + 3 x^{2} + 3 x - 1 = 0
