Answer 14

Determine whether the following polynomials can be factored by grouping. If so, factor the polynomials showing all work

a.2c2 + 6cd + 5c + 15d
b.3a2 + 6ab + 4a + 4b

Answer 15

2c^2 + 6cd + 5c + 15d
(2c^2 + 5c) + (6cd + 15d)
c(2c+5)+3d(2c+5)
(c+3d)(2c+5)

Answer 16

only A can Be grouped the second one is not .
