Question

factor polynomial
3rs-2r-3s+2

Answer 1

try factoring by grouping:

3rs-2r-3s+2
= 3rs - 3s - 2r + 2
= 3s(r - 1) - 2(r - 1)
notice (r - 1) is common to each term so can you continue?

Answer 2

no still confused

Answer 3

well as (r - 1) multiplies both 3s and -2 we can 'take (r - 1) out' and write :

(r - 1)(3s - 2)

and this is the final answer

Answer 4

but i though you took out r-1
