Question

Which expression is equivalent to ( n + 3) (2n - 5)?

Answer 1

Explanation:

`(n + 3)(2n - 5)\\(n * 2n) + (n * -5) + (3 * 2n) + (3 * -5)\\(2n^2 ) + (-5n) + (6n) + (-15)\\2n^2 + n - 15`

Answer 2

2n² + n - 15

Explanation:

(n + 3) (2n - 5)

= 2n² - 5n + 6n - 15

= 2n² + n - 15

So, the answer is 2n² + n - 15
