Which expression represents a quadratic expression in complete factored form?

A. (x + 4) (x - 3)

B. (2x + 4) (x+3)

c. (x - 2) + (x + 3)

D. (x - 1) (3x - 9)

a

Step-by-step explanation:

x+4 and x-3 cant be simplified any further therefore making it completely factored.

Answer: A. (x + 4) (x - 3)

(x + 4) (x - 3) is the only answer that cannot be factored.

2 can be factored out of 2x + 4

(2x + 4) (x - 3)

factored as 2 (x + 4) (x - 3)

this one isn't even multiplication:

(x - 2) + (x + 3)

It can be written as 2x + 1

3 can be factored out of 3x - 9

(x - 2) (3x - 9)

It factors into 3 (x - 2) (x - 9)

But nothing can be factored out of (x + 4) (x - 3)
