Q. Factor the expression completely.x2y3−xy4Answer:
Identify Common Factors: Identify the common factors in both terms of the expression x2y3−xy4. Both terms have an 'x' and a 'y' in common. The smallest power of 'x' is 1 and the smallest power of 'y' is 3.
Factor Out Common Factors: Factor out the common factors from both terms.The greatest common factor (GCF) is xy3. Factoring this out, we get:xy3(x−y)
Check Factored Expression: Check to ensure that when the factored expression is expanded, it results in the original expression.(xy3)(x−y)=x2y3−xy4This matches the original expression, so there is no math error.
