(x+4)^2-3=22

解答

(x + 4)^{2} - 3 = 22

解答

x = 1, x = - 9

求解步骤

(x + 4)^{2} - 3 = 22

将

3

到右边

(x + 4)^{2} = 25

对于

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

解为

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

解

x + 4 = 25 : x = 1

解

x + 4 = - 25 : x = - 9

二次方程组的解是:

x = 1, x = - 9

x^{2} - 12 x = - 15

8 b + b^{2} - 10 = 0

(-12/13)^2+x^2=1

(- \frac{12}{13})^{2} + x^{2} = 1

\frac{1}{2} x^{2} + 7 x = 0

x^2-3x-44=-3x+5-3x+5

x^{2} - 3 x - 44 = - 3 x + 5 - 3 x + 5
