solvefor x,x^2+9y^2=0

解

解く

x, x^{2} + 9 y^{2} = 0

解

x = 3 - y^{2}, x = - 3 - y^{2}

解答ステップ

x^{2} + 9 y^{2} = 0

9 y^{2}

を右側に移動します

x^{2} = - 9 y^{2}

x^{2} = f (a)

の場合, 解は

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

x = - 9 y^{2}, x = - - 9 y^{2}

簡素化

- 9 y^{2} : 3 - y^{2}

簡素化

- - 9 y^{2} : - 3 - y^{2}

x = 3 - y^{2}, x = - 3 - y^{2}

solvefor x,(x^2+y^2)(p^2+q^2)=1

so l v e f or x, (x^{2} + y^{2}) (p^{2} + q^{2}) = 1

solvefor a,a^2*b^2=c^2

so l v e f or a, a^{2} \cdot b^{2} = c^{2}

x^{2} - b^{2} = 0

solvefor x,f=m(x+1)^2+n

so l v e f or x, f = m (x + 1)^{2} + n

9 = 3 m^{2} + 2 (m - 13)
