Question

Does x2 - 18x + 45 and x2 - 6x + 9 share a common factor? Please explain too ;~;

Answer 1

have you tried getting the factors of each of the polynomials?

Answer 2

I factored them both and got (x - 3)(x - 15) and (x-3)^2 if that's what you were asking.

Answer 3

yes, so if

\(\large\color{midnightblue}{ \rm x^2 - 18x + 45 =(x-15)(x-3) }\) and,
\(\large\color{midnightblue}{ \rm x@2 - 6x + 9 =(x-3)(x-3) }\)
then the factor the BOTH have in COMMON is ?

Answer 4

3?

Answer 5

\(\large\color{midnightblue}{ \rm (x-3) }\)

Answer 6

oooh okay thank you!

Answer 7

Anytime
