Đề là \(f\left(x\right)=\left(2^x-1\right)\left(x^2+2x-3\right)\) đúng ko bạn?
\(\left(2^x-1\right)\left(x^2+2x-3\right)=0\)
\(\Leftrightarrow\left[{}\begin{matrix}2^x-1=0\\x^2+2x-3=0\end{matrix}\right.\)
\(\Leftrightarrow\left[{}\begin{matrix}2^x=1\\\left(x-1\right)\left(x+3\right)=0\end{matrix}\right.\)
\(\Rightarrow\left[{}\begin{matrix}x=0\\x=1\\x=-3\end{matrix}\right.\)
