Question

trình bày đầy đủ nha

 

Answer 1

\(=x\left(x-5y\right)-\left(x-5y\right)=\left(x-5y\right)\left(x-1\right)\)

Answer 2

\(b,=\left(x^2-5xy\right)-\left(x-5y\right)\)

\(=x\left(x-5y\right)-\left(x-5y\right)\)

\(\left(x-5y\right)\left(x-1\right)\)

Answer 3

b. (x2-x)-(5xy-5y)

=x(x-1)-5y(x-1)

=(x-5y)(x-1)
