Step-by-step explanation:
23x3
37Factoring: 8x3-37
Theory : A difference of two perfect cubes, a3 - b3 can be factored into
(a-b) • (a2 +ab +b2)
Proof : (a-b)•(a2+ab+b2) =
a3+a2b+ab2-ba2-b2a-b3 =
a3+(a2b-ba2)+(ab2-b2a)-b3 =
a3+0+0-b3 =
a3-b3
Check : 8 is the cube of 2
Check : 37 is not a cube !!
Ruling : Binomial can not be factored as the difference of two perfect cubes
