0=-(0.5)/2+((x-0.5)^2)/3

解答

0 = - \frac{0.5}{2} + \frac{( x - 0.5 ) ^{2}}{3}

解答

x = 1.36602 \dots, x = - 0.36602 \dots

求解步骤

0 = - \frac{0.5}{2} + \frac{( x - 0.5 ) ^{2}}{3}

交换两边

- \frac{0.5}{2} + \frac{( x - 0.5 ) ^{2}}{3} = 0

将

\frac{0.5}{2}

到右边

\frac{( x - 0.5 ) ^{2}}{3} = \frac{0.5}{2}

在两边乘以

3

(x - 0.5)^{2} = 0.75

对于

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

解为

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

解

x - 0.5 = 0.75 : x = 1.36602 \dots

解

x - 0.5 = - 0.75 : x = - 0.36602 \dots

二次方程组的解是:

x = 1.36602 \dots, x = - 0.36602 \dots

3(6x-5)-(6x-5)^2=0

3 (6 x - 5) - (6 x - 5)^{2} = 0

3 (x + 8)^{2} - 12 = 24

7 x^{2} - 18 x + 12 = 0

10x^2+30x-500=0

10 x^{2} + 30 x - 500 = 0
