\(2x^2+x-6\)
\(=2x^2+4x-3x-6\)
\(=2x\left(x+2\right)-3\left(x+2\right)\)
\(=\left(2x-3\right)\left(x+2\right)\)
2x2 + x - 6
= 2x2 + 4x - 3x - 6
= 2x ( x+ 2 ) - 3 ( x+ 2 )
= ( x + 2 ) ( 2x - 3 )
(x+2)(2x-3)
Bạn Nguyễn Tũn bớt thể hiện lại đi
2x2 + x - 6
= 2x2 + 4x - 3x - 6
= 2x ( x+ 2 ) - 3 ( x+ 2 )
= ( x + 2 ) ( 2x - 3 )
khó quá tui ko biết làm..
k cho tui nha
thanks
