Question

Solve for nn²-8n-48=0​

Answer 1

Answer:

n=-4

Step-by-step explanation:

Answer 2

If you solve n^2 - 8n - 48 = 0 by factoring, you'd do this:

1. What multplies to make -48?

    1 (-48)

    2 (-24)

    3 (-16)

    4 (-12)

    6 (-8)

2. Which of those adds to make -8?

    4 + (-12) =-8

3. So n^2 - 8n - 48 = 0 factors as (n+4)(n-12) = 0

4. Set each factor equal to 0

    n+4 = 0           or          n-12 = 0

        n = -4                           n = 12

The two solutions are -4 and 12.
