(x-3)^2-24=0

解答

(x - 3)^{2} - 24 = 0

解答

x = 26 + 3, x = - 26 + 3

+1

十进制

x = 7.89897 \dots, x = - 1.89897 \dots

求解步骤

(x - 3)^{2} - 24 = 0

将

24

到右边

(x - 3)^{2} = 24

对于

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

解为

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

解

x - 3 = 24 : x = 26 + 3

解

x - 3 = - 24 : x = - 26 + 3

二次方程组的解是:

x = 26 + 3, x = - 26 + 3

(2 x + 3) (x - 2) = 4

solvefor x,f=3x^2-5x-p

so l v e f or x, f = 3 x^{2} - 5 x - p

x^{2} + 62.1 x + 1 = 0

x^{2} - a x - 1 = 0

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