(x-1)^2-36=1

解答

(x - 1)^{2} - 36 = 1

解答

x = 37 + 1, x = - 37 + 1

+1

十进制

x = 7.08276 \dots, x = - 5.08276 \dots

求解步骤

(x - 1)^{2} - 36 = 1

将

36

到右边

(x - 1)^{2} = 37

对于

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

解为

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

解

x - 1 = 37 : x = 37 + 1

解

x - 1 = - 37 : x = - 37 + 1

二次方程组的解是:

x = 37 + 1, x = - 37 + 1

流行的例子

4 m^{2} + 6 m = 6 m + 36

x^{2} + x^{2} = 9 2^{2}

(x + 1) (x - 4) = 6

x (2 x) = 1800

(3x+2)^2+(x+4)^2=(2x+6)

(3 x + 2)^{2} + (x + 4)^{2} = (2 x + 6)
