0=(x-4)^2-1

解答

0 = (x - 4)^{2} - 1

解答

x = 5, x = 3

求解步骤

0 = (x - 4)^{2} - 1

交换两边

(x - 4)^{2} - 1 = 0

将

1

到右边

(x - 4)^{2} = 1

对于

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

解为

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

解

x - 4 = 1 : x = 5

解

x - 4 = - 1 : x = 3

二次方程组的解是:

x = 5, x = 3

x^{2} = 2 5^{2} + 1 5^{2}

solvefor x,7x^2+6sqrt(3)xy+13y^2-16=0

so l v e f or x, 7 x^{2} + 63 x y + 13 y^{2} - 16 = 0
