8-3(x+4)^2=-424

解答

8 - 3 (x + 4)^{2} = - 424

解答

x = 8, x = - 16

求解步骤

8 - 3 (x + 4)^{2} = - 424

将

8

到右边

- 3 (x + 4)^{2} = - 432

两边除以

- 3

(x + 4)^{2} = 144

对于

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

解为

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

解

x + 4 = 144 : x = 8

解

x + 4 = - 144 : x = - 16

二次方程组的解是:

x = 8, x = - 16

3 x^{2} - 12 x - 10 = 0

6x-6=-5(x-1)^2-3x^2+3

6 x - 6 = - 5 (x - 1)^{2} - 3 x^{2} + 3

5 x^{2} + 6 x + 7 = 0

(0+2)^2+(y-5)^2=25

(0 + 2)^{2} + (y - 5)^{2} = 25

(a - 7)^{2} + 5 = 55
