Answer
Cannot be factored
Work Step by Step
$3n^2+20n+5$
Factors of 5: 1 and 5, -1 and -5
Factors of 3: 1 and 3, -1 and -3
Since there are no negative coefficients, we will ignore the negative pairs for the factors.
$(3n+1)(n+5)$
$3n*n+3n*5+1*n+5*1$
$3n^2+15n+n+5$
$3n^2+16n+5$
$(3n+5)(n+1)$
$3n*n+3n*1+5*n+5*1$
$3n^2+3n+5n+5$
$3n^2+8n+5$
