\(G=x.\left(x+1\right)^2+x\left(x-5\right)-5\left(x+1\right)^2\)
\(G=\left(x+1\right)^2.\left(x-5\right)+x\left(x-5\right)\)
\(G=\left(x-5\right).\left[\left(x+1\right)^2+x\right]\)
\(G=\left(x-5\right).\left(x^2+2x+1+x\right)\)
\(G=\left(x-5\right).\left(x^2+3x+1\right)\)
Chúc bạn học tốt!!!
F=\(^{x^3}+y-3x^2y+3xy^2-x-y^3\)
F=\(\left(x-y\right)^3+y-x\)
F=\(\left(x-y\right)[\left(x-y\right)^2-1]\)
F=(x-y)(x-y+1)(x-y-1)
E=(2x-3y)(2x+3y)+2(2x-3y)
E=(2x-3y)(2x+3y+2).Còn câu G Đoàn Đức Hiếu giải rồi
