    ~Rewrite - 12n

    -4 * 3n

    ~Rewrite - 20

    -4 * 5

    ~Put together

    -4 * 3n + - 4 * 5

    ~Factor out - 4

    -4 (3n + 5)

    -4 (3n + 5)

    Step-by-step explanation:

    We want to factor the expression:

    -12n - 20

    Look at the two terms, which are - 12n and - 20. Obviously, they don't share an "n", but they do share another number.

    Notice that - 12 can be written as the product of - 4 and 3: - 12 = - 4 * 3. Similarly, - 20 can be written as the product of - 4 and 5: - 20 = - 4 * 5. Since 3 and 5 are prime numbers, we know that - 4 is the biggest factor that - 12 and - 20 share. So, let's factor that out of the expression:

    -12n - 20 = - 4 * [ (-12n/-4) + (-20/-4) ] = - 4 * (3n + 5)

    So, the factored form of this expression is - 4 (3n + 5).
