Answer 1

Answer :

= (3)(-2)3+2(-2)2×(6)+(6)3

= (3×8)+(12×4)+216

= 24+48+216

= 288

Answer 2

Answer:

a) m+ n = m+ n

b) 2m ^2 + 8n

factor out 2

2 ( m ^ 2 + 4n )

c) m^2 - n^2

the difference of square can be factored the rule a^2 - ( a - b) ( a+ b)

( m - n ) ( m+n )

d) 3m ^3 + 2 m ^2 n +3

3m ^3 + 2 nm^ 2+n^3

( m+ n) ( 3m^2 - mn+ n^2)
