solvefor x,x^2=(4R)/3 (2R-(4R)/3)

解答

求解

x, x^{2} = \frac{4 R}{3} (2 R - \frac{4 R}{3})

解答

x = \frac{2 2 R}{3}, x = - \frac{2 2 R}{3}

求解步骤

x^{2} = \frac{4 R}{3} (2 R - \frac{4 R}{3})

化简

\frac{4 R}{3} (2 R - \frac{4 R}{3}) : \frac{8 R ^{2}}{9}

对于

x^{2} = f (a)

解为

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

x = \frac{8 R ^{2}}{9}, x = - \frac{8 R ^{2}}{9}

化简

\frac{8 R ^{2}}{9} : \frac{2 2 R}{3}

化简

- \frac{8 R ^{2}}{9} : - \frac{2 2 R}{3}

x = \frac{2 2 R}{3}, x = - \frac{2 2 R}{3}

流行的例子

u^{2} - 4 u = 12

x^{2} = 0.9

solvefor x,x^2+y^2+z^2-4y-6z+13=0

so l v e f or x, x^{2} + y^{2} + z^{2} - 4 y - 6 z + 13 = 0

4 x^{2} = - 17 x - 4

2 x^{2} - 4 = 88
