Identify Common Factor: Step Title: Identify the Common FactorConcise Step Description: Identify the greatest common factor that can be factored out from both terms in the expression.Step Calculation: The greatest common factor of 5 and −20x2 is 5.Step Output: Greatest common factor: 5
Factor Out Common Factor: Step Title: Factor Out the Greatest Common FactorConcise Step Description: Factor out the greatest common factor from the expression.Step Calculation: Factoring out 5 from the expression gives 5(1−4x2).Step Output: Factored expression: 5(1−4x2)
Recognize Difference of Squares: Step Title: Recognize the Difference of SquaresConcise Step Description: Recognize that the expression inside the parentheses is a difference of squares.Step Calculation: The expression 1−4x2 can be written as (1)2−(2x)2, which is a difference of squares.Step Output: Difference of squares: (1)2−(2x)2
Factor Difference of Squares: Step Title: Factor the Difference of SquaresConcise Step Description: Factor the difference of squares using the formula a2−b2=(a−b)(a+b).Step Calculation: Using the formula, we factor 1−4x2 as (1−2x)(1+2x).Step Output: Factored form of the difference of squares: (1−2x)(1+2x)
Write Final Factored Form: Step Title: Write the Final Factored FormConcise Step Description: Combine the factored difference of squares with the factored out greatest common factor.Step Calculation: The final factored form is 5(1−2x)(1+2x).Step Output: Final factored form: 5(1−2x)(1+2x)
