Q. Factor the expression completely.xy3+x3yAnswer:
Identify GCF: Identify the greatest common factor (GCF) of the terms xy3 and x3y. Both terms have 'x' and 'y' in common. The smallest power of 'x' is 1 and the smallest power of 'y' is also 1. Therefore, the GCF is xy.
Factor out GCF: Factor out the GCF from the expression.xy(y2+x2)We took out xy from both terms, leaving us with y2 from the first term and x2 from the second term.
Check for further factorization: Check if the remaining expression y2+x2 can be factored further.The expression y2+x2 is a sum of squares, which cannot be factored over the real numbers. Therefore, the expression is already in its simplest factored form.
