(x+5)^2+13=62

解答

(x + 5)^{2} + 13 = 62

解答

x = 2, x = - 12

求解步骤

(x + 5)^{2} + 13 = 62

将

13

到右边

(x + 5)^{2} = 49

对于

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

解为

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

解

x + 5 = 49 : x = 2

解

x + 5 = - 49 : x = - 12

二次方程组的解是:

x = 2, x = - 12

流行的例子

x^{2} - 5 x + 2 = 1 - \frac{x}{2}

0 = x^{2} - x + 12

2 - 8 x^{2} = 0

s^{2} + 9 s + 18 = 0

0=-4.9t^2+12t+15

0 = - 4.9 t^{2} + 12 t + 15
