solvefor t,x= 1/2 at^2

解答

求解

t, x = \frac{1}{2} a t^{2}

解答

t = \frac{2 x}{a}, t = - \frac{2 x}{a}; a \neq = 0

求解步骤

x = \frac{1}{2} a t^{2}

交换两边

\frac{1}{2} a t^{2} = x

在两边乘以

2

a t^{2} = 2 x

两边除以

a; a \neq = 0

t^{2} = \frac{2 x}{a}; a \neq = 0

对于

x^{2} = f (a)

解为

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

t = \frac{2 x}{a}, t = - \frac{2 x}{a}; a \neq = 0

solvefor y,x=y^2-y

so l v e f or y, x = y^{2} - y

1 - 3 x^{2} = 2 (x - 1)

m(x)=3x^2+x-5,m(1/2)

m (x) = 3 x^{2} + x - 5, m (\frac{1}{2})

- x^{2} = - 81 x

(11x-1)^2-2(11x-1)-3=0

(11 x - 1)^{2} - 2 (11 x - 1) - 3 = 0
