Question

Simplify the polynomial expression given below.

(2x − 1)(2x2 + 5x + 3) + (3x + 6)

Answer 1

Its A

Explanation:

Just took it.

Answer 2

`4x^(3)+8x^(2) +4x+3`

Explanation:

Hello

To simplify the polynomial we must eliminate the parentheses

by definition

`ax^(n)*bx^(m) =abx^(n+m)`

`(2x-1)(2x^(2) +5x+3)+(3x+6)\\(4x^(3) +10x^(2) +6x-2x^(2) -5x-3)+(3x+6)\\\\We\ add\ the\ similar\ terms\\\\(4x^(3)+8x^(2) +x-3)+(3x+6)\\\\4x^(3)+8x^(2) +4x+3`

I hope it helps

Have a great day
