solvefor x,((x^2+m^2))/v =((v^2-s))/m

解答

求解

x, \frac{( x ^{2} + m ^{2} )}{v} = \frac{( v ^{2} - s )}{m}

解答

x = \frac{( v ^{2} - s ) v}{m} - m^{2}, x = - \frac{( v ^{2} - s ) v}{m} - m^{2}; v \neq = 0

求解步骤

\frac{( x ^{2} + m ^{2} )}{v} = \frac{( v ^{2} - s )}{m}

\frac{x ^{2} + m ^{2}}{v} = \frac{v ^{2} - s}{m}

在两边乘以

v

x^{2} + m^{2} = \frac{( v ^{2} - s ) v}{m}; v \neq = 0

将

m^{2}

到右边

x^{2} = \frac{( v ^{2} - s ) v}{m} - m^{2}; v \neq = 0

对于

x^{2} = f (a)

解为

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

x = \frac{( v ^{2} - s ) v}{m} - m^{2}, x = - \frac{( v ^{2} - s ) v}{m} - m^{2}; v \neq = 0

solvefor x,x^2+y^2+z^2=x+y+z+84

so l v e f or x, x^{2} + y^{2} + z^{2} = x + y + z + 84

solvefor x,[3p+1]*x^2+2[p+1]*x+p=0

so l v e f or x, [3 p + 1] \cdot x^{2} + 2 [p + 1] \cdot x + p = 0

m/n*x^2+n/m =1-2x

\frac{m}{n} \cdot x^{2} + \frac{n}{m} = 1 - 2 x

e = d^{2} \cdot 10 + d^{1}

solvefor y,x^3+y^2-27x-10y+30=0

so l v e f or y, x^{3} + y^{2} - 27 x - 10 y + 30 = 0
