Question

factor
x^2 - 5x - 6
im doing factoring and g.c.f i read that prime if for those who do not have a gfc but here prime is not an option i have
x + 2
x+5
x-6
I want to know if this is just factoring and the gcf is not involved and how thanks

Answer 1

the factor of x^2-5x-6 is (x-6)(x+1)

u only use gcf when all the coefficients and the constant can be divisible by a integer

Answer 2

im still confused

Answer 3

if (x-a) is a factor of any polynomial P(x), then P(a) = 0.

SO check from the options for which "a's" the above polynomial gets reduced to zero.

Answer 4

me thinks, x-6.
what do you think?

Answer 5

yea me too thx ,,
