Q. Factor 64b−16c to identify the equivalent expressions.Choose 2 answers:(A) 16(4b−c)(B) 4(16b−4c)(C) 8(8b+2c)(D) 2(32b−8c)
Identify GCF: Step Title: Identify the Greatest Common Factor (GCF)Concise Step Description: Determine the greatest common factor that can be factored out from both terms in the expression 64b−16c.Step Calculation: The GCF of 64 and 16 is 16.Step Output: GCF: 16
Factor Out GCF: Step Title: Factor Out the GCFConcise Step Description: Factor out the GCF from the expression to simplify it.Step Calculation: Factoring out 16 from 64b−16c gives us 16(4b−c).Step Output: Factored Expression: 16(4b−c)
Verify Factored Expression: Step Title: Verify the Factored ExpressionConcise Step Description: Check if the factored expression is equivalent to the original expression by distributing the GCF.Step Calculation: Distributing 16 to (4b−c) gives us 16×4b−16×c, which simplifies to 64b−16c.Step Output: Verified Expression: 64b−16c
Compare with Choices: Step Title: Compare with the Answer ChoicesConcise Step Description: Compare the factored expression with the given answer choices to identify the equivalent expressions.Step Calculation: The factored expression 16(4b−c) matches with choice A. Now, let's check if any other choices are equivalent.Step Output: Equivalent Expression: A
Check Other Choices: Step Title: Check Other Answer ChoicesConcise Step Description: Check if any other answer choices are equivalent to the factored expression by simplifying them.Step Calculation: Choice B simplifies to 4×16b−4×4 which is 64b−16c, so choice B is also equivalent. Choices C and D do not simplify to the original expression.Step Output: Equivalent Expression: B
