Question

(2x + 1)(x-2)(x + 3) ​

Answer 1

`2x^(3) + 3x^(2) - 11x - 6`

Explanation:

(2x + 1)(x - 2)(x + 3)

Since there is multiplication i between all of these, I will multiply the first 2, then multiply it with the last one:

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

(
`2x^(2) -3x - 2` ) (x + 3) =
`2x^(3) +3x^(2) -11x - 6`

Answer 2

2x^3 + 3x^2 -11x -6

Explanation:

(2x + 1)(x-2)(x + 3) ​

(2x^2 -4x + x - 2)(x + 3)

(2x^2 -3x - 2)(x + 3)

2x^3 - 3x^2 - 2x + 6x^2 - 9x - 6

2x^3 + 3x^2 -11x -6
