solvefor t,((t^2))/((r^3))=k

解答

求解

t, \frac{( t ^{2} )}{( r ^{3} )} = k

解答

t = r k r, t = - r k r; r \neq = 0

求解步骤

\frac{( t ^{2} )}{( r ^{3} )} = k

在两边乘以

r^{3}

t^{2} = k r^{3}; r \neq = 0

对于

x^{2} = f (a)

解为

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

t = k r^{3}, t = - k r^{3}; r \neq = 0

化简

k r^{3} : r k r

化简

- k r^{3} : - r k r

t = r k r, t = - r k r; r \neq = 0

7 - 3 x^{2} = 4

solvefor x,1y^2+x^2-xy+4x-5y-2=0

so l v e f or x, 1 y^{2} + x^{2} - x y + 4 x - 5 y - 2 = 0

solvefor x,x^2-6x+7=m(2x-3)

so l v e f or x, x^{2} - 6 x + 7 = m (2 x - 3)

x^{2} + 7 + 12 = 0

solvefor a,(a+2)^2+5=(b+2)^2+5

so l v e f or a, (a + 2)^{2} + 5 = (b + 2)^{2} + 5
