Answer:

$4x^{3}+8x^{2} +4x+3$

Step-by-step 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
