what is the answer to 3n^2-8n-3

Answer 1

Set to zero and factor (3n+1)(n-3)=0

So solutions are

3n+1=0. n-3=0

3n=-1. n=3

n=(-1/3)

Answer 2

This expression factors as (n-3)(3n+1)

When you set each equal to zero,

you get

n-3 = 0 so n=3

3n + 1 = 0 so n = -1/3

The two solutions are

3, -1/3
