Identify Expression Type: Step Title: Identify the Type of ExpressionConcise Step Description: Recognize that the expression is a difference of squares.Step Calculation: The expression 1−4x4y2 can be seen as a2−b2 where a=1 and b=(2x2y).Step Output: Recognized as a difference of squares.
Apply Formula: Step Title: Apply the Difference of Squares FormulaConcise Step Description: Use the formula a2−b2=(a+b)(a−b) to factor the expression.Step Calculation: Factoring 1−4x4y2 using the formula gives us (1+2x2y)(1−2x2y).Step Output: Factored form is (1+2x2y)(1−2x2y).
