5(2x-10)^2-23=32

解答

5 (2 x - 10)^{2} - 23 = 32

解答

x = \frac{11 + 10}{2}, x = \frac{- 11 + 10}{2}

+1

十进制

x = 6.65831 \dots, x = 3.34168 \dots

求解步骤

5 (2 x - 10)^{2} - 23 = 32

将

23

到右边

5 (2 x - 10)^{2} = 55

两边除以

5

(2 x - 10)^{2} = 11

对于

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

解为

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

解

2 x - 10 = 11 : x = \frac{11 + 10}{2}

解

2 x - 10 = - 11 : x = \frac{- 11 + 10}{2}

二次方程组的解是:

x = \frac{11 + 10}{2}, x = \frac{- 11 + 10}{2}
