Q. Factor 48−8x to identify the equivalent expressions.Choose 2 answers:A) 3(16−8x)B) 2(24−4x)C) 8(6−x)D) 4(12−2x)
Identify GCF: Identify the greatest common factor (GCF) of the terms in the expression 48−8x. The GCF of 48 and 8x is 8.
Factor out GCF: Factor out the GCF from the expression. This means we divide each term by 8 and place the 8 outside of the parentheses.So, 48 divided by 8 is 6, and −8x divided by 8 is −x.
Write factored expression: Write the factored expression as 8(6−x).
Check answer choices: Check the answer choices to see which ones are equivalent to 8(6−x). A) 3(16−8x) is not equivalent because 3×16 is 48 but 3×−8x is −24x, not −8x. B) 2(24−4x) is not equivalent because 2×24 is 48 but 3(16−8x)0 is −8x, which is correct. C) 8(6−x) is equivalent because it is the expression we derived. D) 3(16−8x)3 is not equivalent because 3(16−8x)4 is 48 but 3(16−8x)6 is 3(16−8x)7, not −8x.
Conclude equivalent expressions: Conclude that the equivalent expressions for factoring 48−8x are B) 2(24−4x) and C) 8(6−x).
