solvefor x,2x^2+y^3=0

解答

求解

x, 2 x^{2} + y^{3} = 0

解答

x = i \frac{y ^{3}}{2}, x = - i \frac{y ^{3}}{2}

求解步骤

2 x^{2} + y^{3} = 0

将

y^{3}

到右边

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

两边除以

2

x^{2} = - \frac{y ^{3}}{2}

对于

x^{2} = f (a)

解为

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

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

化简

- \frac{y ^{3}}{2} : i \frac{y ^{3}}{2}

化简

- - \frac{y ^{3}}{2} : - i \frac{y ^{3}}{2}

x = i \frac{y ^{3}}{2}, x = - i \frac{y ^{3}}{2}

a x^{2} = c

2x-8=x^2+13x+20

2 x - 8 = x^{2} + 13 x + 20

completesquare 6r^2+6r+12=0

co m pl e t es q u a re 6 r^{2} + 6 r + 12 = 0

(200+4x)(50+x)=10000

(200 + 4 x) (50 + x) = 10000

solvefor a,(x^2+y^2)^2=a^2(x^2-y^2)

so l v e f or a, (x^{2} + y^{2})^{2} = a^{2} (x^{2} - y^{2})
