Question

Find the product.
(x - y)(8x + y)
Enter the correct answer.

Answer 1

8x² - 7xy - y²

Explanation:

(x - y)(8x + y)

Here we need to foil in order to find the product.

To do so:

• We need to multiply (x)(8x) + (x)(y) + (-y)(8x) + (-y)(y)
• Simplifying we get: 8x² + xy - 8xy - y²
• Combining like terms we get: 8x² - 7xy - y²
