(x-4)^2-3=6

解答

(x - 4)^{2} - 3 = 6

解答

x = 7, x = 1

求解步骤

(x - 4)^{2} - 3 = 6

将

3

到右边

(x - 4)^{2} = 9

对于

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

解为

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

解

x - 4 = 9 : x = 7

解

x - 4 = - 9 : x = 1

二次方程组的解是:

x = 7, x = 1

流行的例子

(w + 1)^{2} - 32 = 0

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

b^{2} = 0

a x^{2} - 2 x + 4 = 0

solvefor x,f=x^2-kx+k^2

so l v e f or x, f = x^{2} - k x + k^{2}
