Question Simplify the expression x2−2xy+y2x2y2 Evaluate (x−y)2(xy)2To raise a product to a power,raise each factor to that power (x−y)2x2y2Solution x2−2xy+y2x2y2 Show Solution Find the excluded values x=y Evaluate (x−y)2(xy)2To find the excluded values,set the denominators equal to 0 (x−y)2=0The only way a power can be 0 is when the base equals 0 x−y=0Move the expression to the right side x=0+ySolution x=y Show Solution
