Question

simplify (a+3³) - (a-3³)​

Answer 1

Step-by-step explanation:

We get:

(a+3)3+(a−3)3

⇒(a3+3a2⋅3+3a(3)2+(3)3)−(a3−3a2⋅3+3a(3)2−(3)3)

⇒a3+9a2+3a⋅9+27−a3+9a2−3a⋅9+27

⇒18a2+27

⇒9(2a2+3)

~Hope this helps! :)

Answer 2

( a+ 3cube) - ( a - 3cube )

= a + 27 - ( a - 27)
= a+27 - a + 27
= a - a +27 + 27
= 0 + 54
= 54
