Factor (x+y)2(Note: x2 = x2)
Explanation
The given expression is a binomial squared, which means it represents the square of the sum of two terms (x and y in this case). To expand a binomial squared, we use the formula (a+b)² = a² + 2ab + b². Applying this formula to the given expression, we get x² + 2xy + y². Therefore, the correct answer is x² + 2xy + y².
38.
Factor (x-y)2(Note: x2 = x2)
Explanation
The expression (x-y)2 represents the square of the binomial (x-y). This means that we need to multiply (x-y) by itself. Using the formula for squaring a binomial, we get x2 - 2xy + y2. This is the expanded form of (x-y)2, which is the correct answer.
39.
Factor (x+y)(x+y)(Note: x2 = x2)
Explanation
The given expression is a result of multiplying (x+y) by itself twice. When we expand the expression, we use the distributive property to multiply each term in the first set of parentheses (x+y) by each term in the second set of parentheses (x+y). This results in x multiplied by x (x^2), x multiplied by y (xy), y multiplied by x (xy), and y multiplied by y (y^2). Combining like terms, we get the final answer x^2+2xy+y^2.
40.
Factor (x+y)(x-y)(Note: x2 = x2)
Explanation
The given expression is a product of three factors: (x+y), (x-y), and (x^2-y^2). The first two factors are the difference of squares, which can be simplified to x^2-y^2. Therefore, the correct answer is x^2-y^2.
