2(x-1)^2=-16

解答

2 (x - 1)^{2} = - 16

解答

x = 22 i + 1, x = - 22 i + 1

求解步骤

2 (x - 1)^{2} = - 16

两边除以

2

(x - 1)^{2} = - 8

对于

(g (x))^{2} = f (a)

解为

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

解

x - 1 = - 8 : x = 22 i + 1

解

x - 1 = - - 8 : x = - 22 i + 1

二次方程组的解是:

x = 22 i + 1, x = - 22 i + 1

6x^2-194x+120=0

6 x^{2} - 194 x + 120 = 0

25 x^{2} + 1 = 6 x

15 p^{2} - 3 p = 0

x^{2} - 20 x + 25 = 0

solvefor x,1-2x-x^2cos(y)=0

so l v e f or x, 1 - 2 x - x^{2} cos (y) = 0
