solvefor m+2n^2=7m,n

解答

求解

m + 2 n^{2} = 7 m, n

解答

n = 3 m, n = - 3 m

求解步骤

m + 2 n^{2} = 7 m

将

m

到右边

2 n^{2} = 6 m

两边除以

2

n^{2} = 3 m

对于

x^{2} = f (a)

解为

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

n = 3 m, n = - 3 m

流行的例子

x^{2} - 6 x + 2 = 2

e^{2} + 7 e - 60 = 0

-6x^2+78x-240=0

- 6 x^{2} + 78 x - 240 = 0

- \frac{1}{2} x^{2} + x + 4 = 0

因式分解 2x^2-x=0

f a c t or 2 x^{2} - x = 0
