Question

17. Which of the following is a factor of both x^2 - x - 6 and x^2- 5x+6?
A x-3
B. x- 2
C. x+2
D. x+3​

Answer 1

Step-by-step explanation:

For the equation $x^{2} - x - 6$, factoring gives us the following:

$(x - 3)(x + 2)$

For the equation $x^{2} - 5x + 6$, factoring gives us the following:

$(x - 3)(x - 2)$

From this, we see that the common factor is $(x - 3)$
