Answer 1

Làm đúng tick đúng+follow nhaaa

Answer 2

hi

Answer 3

\(2x+5\sqrt{x}-7=\left(2x-2\sqrt{x}\right)+\left(7\sqrt{x}-7\right)=\left(\sqrt{x}-1\right)\left(2\sqrt{x}+7\right)\)

Answer 4

\(3x-7\sqrt{x}+4=\left(\sqrt{x}-1\right)\left(3\sqrt{x}-4\right)\)

Answer 5

\(4x-4\sqrt{x}-8=4\left(x-\sqrt{x}-2\right)=4\left(\sqrt{x}+1\right)\left(\sqrt{x}-2\right)\)

nhớ hứa nha bạn

Answer 6

\(2x+5\sqrt{x}-7=\left(2\sqrt{x}+7\right)\left(\sqrt{x}-1\right)\)

\(3x-7\sqrt{x}+4=\left(\sqrt{x}-1\right)\left(3\sqrt{x}-4\right)\)

\(4x-4\sqrt{x}-8=4\left(x-\sqrt{x}-2\right)=4\left(\sqrt{x}-2\right)\left(\sqrt{x}+1\right)\)
