solvefor x,x^2+y^2=r(x)^2

解答

求解

x, x^{2} + y^{2} = r (x)^{2}

解答

x = i \frac{y 1 - r}{1 - r}, x = - i \frac{y 1 - r}{1 - r}; r \neq = 1

求解步骤

x^{2} + y^{2} = r x^{2}

将

y^{2}

到右边

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

将

r x^{2}

para o lado esquerdo

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

分解

x^{2} - r x^{2} : x^{2} (1 - r)

x^{2} (1 - r) = - y^{2}

两边除以

1 - r; r \neq = 1

x^{2} = - \frac{y ^{2}}{1 - r}; r \neq = 1

对于

x^{2} = f (a)

解为

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

x = - \frac{y ^{2}}{1 - r}, x = - - \frac{y ^{2}}{1 - r}; r \neq = 1

化简

- \frac{y ^{2}}{1 - r} : i \frac{y 1 - r}{1 - r}

化简

- - \frac{y ^{2}}{1 - r} : - i \frac{y 1 - r}{1 - r}

x = i \frac{y 1 - r}{1 - r}, x = - i \frac{y 1 - r}{1 - r}; r \neq = 1

solvefor x,x^2+y^2+z^2-4x+12y-14z+40=0

so l v e f or x, x^{2} + y^{2} + z^{2} - 4 x + 12 y - 14 z + 40 = 0
