Question

could someone please help with this?

factor 15xy−45x−6y+18

Answer 1

well, let us group them first

\(\bf 15xy-45x-6y+18\implies (15xy-45x)-(6y{\color{brown}{ -}}18)\)

so... any common factor for the first group?
any common factor for the second group?

Answer 2

notice, once you group the 6y+18, becomes -(6y-18)
because - * + = -
and - * - = +

Answer 3

for the first group, it would be 15x right?

to make 15x ( y - 3 )

and then for the second group, it'd be -6 ( y - 3 ) ?
