Answer 1

Đề PTĐTTNT à bạn ?

\(x+2\sqrt{x}-3=x-\sqrt{x}+3\sqrt{x}-3=\sqrt{x}\left(\sqrt{x}-1\right)+3\left(\sqrt{x}-1\right)=\left(\sqrt{x}-1\right)\left(\sqrt{x}+3\right)\)

Answer 2

\(x+3\sqrt{x}-\sqrt{x}-3=\sqrt{x}\left(\sqrt{x}-1\right)+3\left(\sqrt{x}-1\right)=\left(\sqrt{x}+3\right)\left(\sqrt{x}-1\right)\)
