Question

PLEASE HELP!!

Find the Zeros

f(x) = x^2 + 4x + 3

Factoring Trinomials
n^2 - n - 56

Answer 1

-1 and -3

(n+7)(n-8)

Explanation:

1. Find the Zeros

`f(x)=x^(2) +4x+3`

`f(x)=\left(x+1\right)\left(x+3\right)`

`x+1=0\\x=-1\\x+3=0\\x=-3`

2. Factoring Trinomials

`f(x)=n^(2) -n-56`

`f(x)=\left(n+7\right)\left(n-8\right)`

`n+7=0\\n=-7\\n-8=0\\n=8`
