solvefor s,3as^2-an^2=0

解答

求解

s, 3 a s^{2} - a n^{2} = 0

解答

s = \frac{n}{3}, s = - \frac{n}{3}; a \neq = 0

求解步骤

3 a s^{2} - a n^{2} = 0

将

a n^{2}

到右边

3 a s^{2} = n^{2} a

两边除以

3 a; a \neq = 0

s^{2} = \frac{n ^{2}}{3}; a \neq = 0

对于

x^{2} = f (a)

解为

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

s = \frac{n ^{2}}{3}, s = - \frac{n ^{2}}{3}; a \neq = 0

化简

\frac{n ^{2}}{3} : \frac{n}{3}

化简

- \frac{n ^{2}}{3} : - \frac{n}{3}

s = \frac{n}{3}, s = - \frac{n}{3}; a \neq = 0
