✔ 最佳答案
2x^3 + 2x^6=2x^3(1+x^3)
=2x^3(1+x)(1-x+x^2) answer//

a^3 + b^3 = (a + b)(a^2 - ab + b^2)
2x^3 + 2x^6
= 2(x^3 + x^6)
= 2x^3(1 + x^3)
= 2x^3(1^3 + x^3)
= 2x^3(1 + x)(1^2 - 1*x + x^2)
= 2x^3(1 + x)(1 - x + x^2)
2x^3 + 2x^6
= 2(x^3 + x^6)
= 2x^3(1 + x^3)
= 2x^3(1^3 + x^3)
= 2x^3(1 + x)(1^2 - 1*x + x^2)
= 2x^3(1 + x)(1 - x + x^2)

maths indices rules
1. a^m + a^n = a^m+n
therefore 2x^3 + 2x^6 = 2x^9
1. a^m + a^n = a^m+n
therefore 2x^3 + 2x^6 = 2x^9

2x^3 + 2x^6 = 2x^3(1 + x^3) = 2x^3(x -1)(x^2 + x + 1)

2x^3 + 2x^6 = 2x^3 (1 + x^3)
= 2x^3 [(1)^3 + (x)^3]
As,
a^3 + b^3 = (a + b) (a^2 - ab + b^2)
So, the answer would be:
= 2x^3 (1 + x) (1 - x + x^2)
= 2x^3 [(1)^3 + (x)^3]
As,
a^3 + b^3 = (a + b) (a^2 - ab + b^2)
So, the answer would be:
= 2x^3 (1 + x) (1 - x + x^2)

Krishnan, ans would be 2x^3 ( 1 + x^3) => (2x^3 )( 1 + x)( 1 - x +x^2)
And if the Q is like this (2x)^3 + (2x)^6
then,ans is
((2x)^3)(1 + (2x)^3) =>(2x^3 )( 1 + 2x)( 1 - 2x +(2x)^2)
=>8(x^3)( 1 + 2x)( 1 - 2x +4(x)^2)
note: ( 1 + x^3) is of the form (a^3 + b^3) = (a+b)(a^2-ab+b^2)
And if the Q is like this (2x)^3 + (2x)^6
then,ans is
((2x)^3)(1 + (2x)^3) =>(2x^3 )( 1 + 2x)( 1 - 2x +(2x)^2)
=>8(x^3)( 1 + 2x)( 1 - 2x +4(x)^2)
note: ( 1 + x^3) is of the form (a^3 + b^3) = (a+b)(a^2-ab+b^2)

2x^3 + 2x^6 =2x^3(1 + x^3)
= 2x^3(1 + x)(1-x+x^2)
= 2x^3(1 + x)(1-x+x^2)
