(2(m+1)^2)/3 =9

解答

\frac{2 ( m + 1 ) ^{2}}{3} = 9

解答

m = \frac{3 3}{2} - 1, m = - \frac{3 3}{2} - 1

+1

十进制

m = 2.67423 \dots, m = - 4.67423 \dots

求解步骤

\frac{2 ( m + 1 ) ^{2}}{3} = 9

在两边乘以

3

2 (m + 1)^{2} = 27

两边除以

2

(m + 1)^{2} = \frac{27}{2}

对于

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

解为

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

解

m + 1 = \frac{27}{2} : m = \frac{3 3}{2} - 1

解

m + 1 = - \frac{27}{2} : m = - \frac{3 3}{2} - 1

二次方程组的解是:

m = \frac{3 3}{2} - 1, m = - \frac{3 3}{2} - 1

solvefor x,y=a^logx^2

so l v e f or x, y = a^{l} o g x^{2}

solvefor x,(x^2+y^2-1)3-x^2y^2=0

so l v e f or x, (x^{2} + y^{2} - 1) 3 - x^{2} y^{2} = 0

a^2*(x-b)-b^2*(x-a)=x^2*(a-b)

a^{2} \cdot (x - b) - b^{2} \cdot (x - a) = x^{2} \cdot (a - b)

2 x - 4 - x^{2} + 4 = 0

solvefor a,a^2+b^2+c^2=a+c-1/2

so l v e f or a, a^{2} + b^{2} + c^{2} = a + c - \frac{1}{2}
