Answer:

(x + 3) (x - 3)

Step-by-step explanation:

We know that;

a = 1

b = 0

c = -9

We also know that;

p*q = -9

p + q = 0

In this case, it would make the p value 3, and q value -3

The factorized form would be;

(x + p) (x + q)

=> (x + (3)) (x + (-3))

=> (x + 3) (x - 3)

So therefore, the factorized form;

(x + 3) (x - 3)

Hope this helps!
