Question

Find the product.

(n + 7)(n - 2)

n² - 5n - 14
n² + 5n - 14
n² - 5n + 14

Answer 1

(n+7)(n-2)
=n•n+(-2)•n+7•n+7•(-2)
=n²-2n+7n-14
=n²+5n-14. In conclusion, the product of (n+7) and (n-2) or (n+7)(n-2)=n²+5n-14. Hope it help!

Answer 2

The answer is n^2 + 5n - 14.



`(n+7)(n-2)\\\\n*n+(-2)*n+7*n+7*(-2)\\\\n^(2)-2n+7n-14\\\\n^(2)+5n-14`
