Question

. Simplify (4x + 2)3.

Answer 1

Explanation:

Multiply 3 times 4x which gives you 12. Multiply 3 times 2 which gives you 6. Your final answer is 12x+6

Answer 2

`(4x+2)^3=64x^3+96x^2+48x+8`

Explanation:

Given : Expression
`(4x+2)^3`

To find : Simplify the expression ?

Solution :

Expression
`(4x+2)^3`

Applying cubic identity,

`(a+b)^3=a^3+b^3+3a^2b+3ab^2`

`(4x+2)^3=(4x)^3+(2)^3+3(4x)^2(2)+3(4x)(2)^2`

`(4x+2)^3=64x^3+8+96x^2+48x`

`(4x+2)^3=64x^3+96x^2+48x+8`

Therefore, Simplification is
`(4x+2)^3=64x^3+96x^2+48x+8`
