Question

factories ( x- 2y )² -6 ( x - 2y ) + 5​

Answer 1

Answer:

Step-by-step explanation:

( x- 2y )² -6 ( x - 2y ) + 5​

take (x - 2y) common directly

(x - 2y) ( x - 2y - 6) + 5

or

( x- 2y )² -6 ( x - 2y ) + 5​

open brackets by applying identity (a - b)² = a² + b² - 2ab

x² + 4y² - 4xy - 6x + 12y + 5

take common x and y:

x(x -4y - 6) + 4y(y + 2) + 5
