Is there anyway to simplify this? ?

Question

3a(2a-b) - (2a+b)

Answer 1

3a(2a - b) - (2a + b)

= 3a*2a - 3a*b - 2a - b

= 6a^2 - 3ab - 2a - b

Answer 2

if you started with 6a^2 - 3ab - 2a + b

then you factored it wrong...

it should be 3a(2a - b) - (2a -b)

then it's

(2a-b)(3a-1)

Answer 3

yes there is its called foiling. its reduced to

6a^2-3ab-2a-b

Answer 4

6a^2 - 3ab - 2a + b=

(6a^2 - 3ab) - (2a - b)=

3a(2a-b)-(2a-b)=

(2a-b)(3a-1).
