Q. Factor the expression completely.8x3+18xAnswer:
Identify GCF of terms: Identify the greatest common factor (GCF) of the terms in the expression 8x3 and 18x. The GCF of 8 and 18 is 2. Both terms also have an x in common, so the GCF is 2x.
Factor out GCF: Factor out the GCF from the expression. 2x(4x2+9)
Check for further factoring: Check if the remaining expression inside the parentheses can be factored further.The expression 4x2+9 is a sum of squares and cannot be factored over the real numbers.
