solvefor x, x/a x-c=r

解答

求解

x, \frac{x}{a} x - c = r

解答

x = a r + c, x = - a r + c; a \neq = 0

求解步骤

\frac{x}{a} x - c = r

将

c

到右边

\frac{x}{a} x = r + c

化简

\frac{x ^{2}}{a} = r + c

在两边乘以

a

\frac{x ^{2} a}{a} = (r + c) a; a \neq = 0

x^{2} = (r + c) a; a \neq = 0

对于

x^{2} = f (a)

解为

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

x = (r + c) a, x = - (r + c) a; a \neq = 0

化简

(r + c) a : a r + c

化简

- (r + c) a : - a r + c

x = a r + c, x = - a r + c; a \neq = 0

流行的例子

y^{2} - 2 y - 2 x + 3 = 0

a f (x) = a x^{2} + 1

16 y^{2} = 9 x

\frac{25}{7} y = (x + 4)^{2}

y^{2} + 4 x - 12 y + 4 = 0
