Q. Factor the expression completely.x5y2−x3y5Answer:
Identify common factors: Identify the common factors in both terms.We have the expression x5y2−x3y5. To factor it completely, we need to find the greatest common factor (GCF) of the two terms. The GCF is the highest power of x and y that is present in both terms.
Determine GCF: Determine the GCF of the two terms.The GCF of x5y2 and x3y5 is x3y2, because x3 is the highest power of x that is present in both terms, and y2 is the highest power of y that is present in both terms.
Factor out GCF: Factor out the GCF from the expression.We can write the original expression as the GCF multiplied by what is left after dividing each term by the GCF.x5y2−x3y5=x3y2(x5−3y2−2−x3−3y5−2)
Simplify expression: Simplify the expression inside the parentheses.Subtract the exponents inside the parentheses, as we have factored out the common factors.x3y2(x2y0−x0y3)Since any number raised to the power of 0 is 1, we have:x3y2(x2⋅1−1⋅y3)This simplifies to:x3y2(x2−y3)
Write final factored expression: Write the final factored expression.The completely factored form of the expression is:x3y2(x2−y3)
