x^2=-3,x^1=7

解

x^{2} = - 3, x^{1} = 7

解

x = 3 i, x = - 3 i

解答ステップ

x^{2} = - 3, x^{1} = 7

x^{2} = f (a)

の場合, 解は

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

x = - 3, x = - - 3

- 3 = 3 i

- - 3 = - 3 i

x = 3 i, x = - 3 i

25m^2-54m+128=0

25 m^{2} - 54 m + 128 = 0

solvefor a,a^2+b^2-2(3a+2b)+13=0

so l v e f or a, a^{2} + b^{2} - 2 (3 a + 2 b) + 13 = 0

solvefor x,x^2+25y^2-2x+10y+2=0

so l v e f or x, x^{2} + 25 y^{2} - 2 x + 10 y + 2 = 0

(((x+5))/5)*(((x-6))/7)=6

(\frac{( x + 5 )}{5}) \cdot (\frac{( x - 6 )}{7}) = 6

a = 36 y^{2}
