Question

Rewrite the quadratic function in intercept or factored form f(n)=-35-2n+n^2

Answer 1

Answer: $f(n)=(n-7)(n+5)$

Step-by-step explanation:

1. You can rewrite the quadratic equation as following:

$f(n)=n^{2}-2n-35$

2. To factor it, you must find two number that when you add them you obtain -2 and when you multiply them you obtain -35. These would be 5 and -7.

3. Therefore, you can write the function in the following intercept form:

$f(n)=(n-7)(n+5)$
