Question

(x+2y)^4 - 1 factories completely ​

Answer 1

Step-by-step explanation:

(x+2y)^4 - 1

Using a²- b² = (a-b)(a+b), factor the expression

[ ( x + 2y)²- 1 ] × [ ( x + 2y)² + 1 ]

Using a²- b² = (a-b)(a+b), factor the expression = ( x + 2y - 1 ) × ( x + 2y + 1 ) × [( x + 2y )² + 1 ]

= ( x + 2y - 1 ) × ( x + 2y + 1 ) × ( x² + 4xy + 4y² + 1 )

Here is your answer...
