Q. Which expression is the result of factoring the expression below by taking out its greatest common factor?\newline8x224=8x^{2}-24=?\newlineChoose 11 answer:\newline(A) 8x(x23)8x(x^{2}-3)\newline(B) 8(x3)8(x-3)\newline(C) 8x(x3)8x(x-3)\newline(D) 8(x23)8(x^{2}-3)
  1. Identify GCF of terms: Identify the greatest common factor (GCF) of the terms in the expression 8x2248x^2 - 24.\newlineThe GCF of 8x28x^2 and 2424 is 88 since 88 is the largest number that divides both terms evenly.
  2. Factor out GCF from each term: Factor out the GCF from each term in the expression.\newlineThe expression 8x2248x^2 - 24 can be factored as 8(x2)8(3)8(x^2) - 8(3), which simplifies to 8(x23)8(x^2 - 3).
  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.\newlineDistributing 88 back into the parentheses gives 8×x28×38 \times x^2 - 8 \times 3, which simplifies to 8x2248x^2 - 24, the original expression.
