(ax+b)^2=c

解答

(a x + b)^{2} = c

解答

x = \frac{c - b}{a}, x = \frac{- c - b}{a}; a \neq = 0

求解步骤

(a x + b)^{2} = c

对于

(g (x))^{2} = f (a)

解为

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

解

a x + b = c : x = \frac{c - b}{a}; a \neq = 0

解

a x + b = - c : x = \frac{- c - b}{a}; a \neq = 0

二次方程组的解是:

x = \frac{c - b}{a}, x = \frac{- c - b}{a}; a \neq = 0

流行的例子

x = x^{2} + x - 1

x^{2} - 4 x - 1 = 3

- x^{2} - 2 x + 24 = 0

x^{2} = - 5 x - 3

x^2=log_{2}(48)-log_{2}(3)

x^{2} = lo g_{2} (48) - lo g_{2} (3)
