a,\(2x^2y-4x^3y^2+10x^2y^3\)
\(=2x^2y\left(1-2xy+5y^2\right)\)
b, \(7\left(2x-1\right)+5x\left(2x-1\right)=\left(2x-1\right)\left(7+5x\right)\)
c, \(13\left(1-x\right)-5x\left(x-1\right)=13\left(1-x\right)+5x\left(1-x\right)\)
\(=\left(1-x\right)\left(13+5x\right)\)
d, \(27x^2\left(y-1\right)-9x^3\left(1-y\right)\)
\(=27x^3\left(y-1\right)+9x^3\left(y-1\right)\)
\(=9x^3\left(y-1\right)\left(3+1\right)=36x^3\left(y-1\right)\)
Chúc bạn học tốt!!!
