Question

Tim x,y biết x-2xy+y=0

Answer 1

\(x\left(1-2y\right)+y-\frac{1}{2}=-\frac{1}{2}\)

\(x\left(1-2y\right)+\frac{1}{2}\left(2y-1\right)=-\frac{1}{2}\)

\(\left(x-\frac{1}{2}\right)\left(1-2y\right)=-\frac{1}{2}\)

Answer 2

\(x\left(1-2y\right)+y-\frac{1}{2}=-\frac{1}{2}\)

\(x\left(1-2y\right)+\frac{1}{2}\left(2y-1\right)=-\frac{1}{2}\)

\(\left(x-\frac{1}{2}\right)\left(1-2y\right)=-\frac{1}{2}\)
