cf:______
$a =$ $b =$ $c =$

Explanation:

Step1: Identify standard form values

For quadratic $ax^2+bx+c$, $a=5$, $b=4$, $c=-9$

Step2: Find GCF of coefficients

Factors of 5: 1, 5; Factors of 4: 1,2,4; Factors of -9: 1,3,9. GCF=1

Step3: Verify factored form

Expand $(x-1)(5x+9)$: $5x^2+9x-5x-9=5x^2+4x-9$

Answer:

CF: $1$
$a = 5$
$b = 4$
$c = -9$
Factored form: $(x-1)(5x+9)$
