5(5x-9)^2-39=41

解答

5 (5 x - 9)^{2} - 39 = 41

解答

x = \frac{13}{5}, x = 1

+1

十进制

x = 2.6, x = 1

求解步骤

5 (5 x - 9)^{2} - 39 = 41

将

39

到右边

5 (5 x - 9)^{2} = 80

两边除以

5

(5 x - 9)^{2} = 16

对于

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

解为

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

解

5 x - 9 = 16 : x = \frac{13}{5}

解

5 x - 9 = - 16 : x = 1

二次方程组的解是:

x = \frac{13}{5}, x = 1
