Question

Answer 1

\(a,=x^2\left(x+3\right):\left(x+3\right)=x^2\\ b,=2\left(x+2\right)\left(x-1\right):\left(x+2\right)=2\left(x-1\right)\\ c,Đề.lỗi\\ d,=\left(x-3\right)\left(x^2+1\right):\left(x-3\right)=x^2+1\\ e,Đề.lỗi\\ f,Đề.lỗi\\ g,=\left(5-3x\right)\left(x^2+3\right):\left(5-3x\right)=x^2+3\\ h,=\left(6x^3-9x^2+8x^2-12x-14x+21\right):\left(2x-3\right)\\ =\left(2x-3\right)\left(3x^2+4x-7\right):\left(2x-3\right)\\ =3x^2+4x-7\)
