\(\left(2x^3-7x^2+13x+2\right):\left(2x-1\right)\)
\(\left[\left(2x^3-x^2\right)-\left(6x^2-3x\right)+\left(10x-5\right)+7\right]:\left(2x-1\right)\)
\(\left[x^2\left(2x-1\right)-3x\left(2x-1\right)+5\left(2x-1\right)+7\right]:\left(2x-1\right)\)
\(\left[\left(x^2-3x+5\right)\left(2x-1\right)+7\right]:\left(2x-1\right)\)
Đến đây bạn tự kết luận nha
