Find the missing factor.

n (n-3) + 2 (n-3) = () (n-3)

This is the concept of quadratic equations. We are required to find the missing factor in the partially factored quadratic equation given;

n (n-3) + 2 (n-3) = () (n-3)

here we proceed as follows;

n (n-3) + 2 (n-3)

when we factor this we get:

(n-3) (n+2)

this can be written as:

(n+2) (n-3)

The answer is (n+2)
