Q. Which expression is the result of factoring the expression below by taking out its greatest common factor?8x2−24=?Choose 1 answer:(A) 8x(x2−3)(B) 8(x−3)(C) 8x(x−3)(D) 8(x2−3)
Identify GCF of terms: Identify the greatest common factor (GCF) of the terms in the expression 8x2−24.The GCF of 8x2 and 24 is 8 since 8 is the largest number that divides both terms evenly.
Factor out GCF from each term: Factor out the GCF from each term in the expression.The expression 8x2−24 can be factored as 8(x2)−8(3), which simplifies to 8(x2−3).
Check factored expression: Check the factored expression to ensure that when the GCF is distributed back into the parentheses, the original expression is obtained.Distributing 8 back into the parentheses gives 8×x2−8×3, which simplifies to 8x2−24, the original expression.
