Q. Factor the expression completely.x4y+x2yAnswer:
Identify Factors: Identify common factors in both terms.Both terms x4y and x2y have x2 and y as common factors.
Factor Out GCF: Factor out the greatest common factor (GCF). The GCF of x4y and x2y is x2y. So we factor x2y out of both terms. x4y+x2y=x2y(x2+1)
Check Further Factoring: Check if the remaining expression inside the parentheses can be factored further.The expression inside the parentheses is x2+1, which cannot be factored further over the real numbers because it does not have real roots.
