please help me quick i've been stuck on this question forever

Question

When the expressions x2 – 9 and x2 – 5x + 6 are factored, what factor do they have in common?

Answer 1

X^2 - 9 = = x^2 - 3^2 = (X-3)(X+3)

X^2 -5X +6 = (X-3)(X-2)

The common factor is (x-3)

Answer 2

Factors of x² -9

(x+3) and (x-3)

Factors of

x^{2 -}5x +6

(x-2) and (x-3)

common factor

(x-3)

so x= 3 is common for both
