Question

solve, x^2-4xy+4y^2

Answer 1

\[x^2-4xy+4y^2\]Split the middle term in half.\[x^2-2xy-2xy+4y^2\]

Answer 2

Now group each of the two terms together, and from those two groups, pullout like terms. \[(x^2-2xy)+(-2xy+4y^2)\]

Answer 3

\[(\color{red}{x}^2 - 2\color{red}{x}y)+(\color{red}{-2y}x+\color{red}{4y}^2)\]

Answer 4

\[x^2-4 x y+4 y^2=(x-2 y)^2 \]
