絕對值方程式求解器(|ax + b| = c)
輸入
|a\,x + b| = c
結果
\begin{aligned} x_1 &= \dfrac{c - b}{a} \\ &= \dfrac{(7) - (-3)}{2} = ? \end{aligned}
\begin{aligned} x_2 &= \dfrac{-c - b}{a} \\ &= \dfrac{-(7) - (-3)}{2} = ? \end{aligned}
\begin{aligned} x_1 &= \dfrac{c - b}{a} \\ &= \dfrac{(7) - (-3)}{2} = ? \end{aligned}
絕對值恆為 ≥ 0,因此當 c < 0 時,|ax + b| = c 沒有實數解。請將 c 改為 ≥ 0 的值再求解。
