solvefor y,x^2+xy^2-y^2=0

解答

求解

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

解答

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

求解步骤

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

将

x^{2}

到右边

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

分解

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

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

两边除以

x - 1; x \neq = 1

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

对于

x^{2} = f (a)

解为

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

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

化简

- \frac{x ^{2}}{x - 1} : i \frac{x - 1 + x}{- 1 + x}

化简

- - \frac{x ^{2}}{x - 1} : - i \frac{x - 1 + x}{- 1 + x}

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

3 x^{2} + 39 = 30 x

因式分解-y+28+y^2=2y+2y^2

f a c t or - y + 28 + y^{2} = 2 y + 2 y^{2}

16 x^{2} + 72 x + 83 = 0

k^{2} + 5 k - 3 = 0

3(3x+5)^2+10=22

3 (3 x + 5)^{2} + 10 = 22
