Question

Multiply the polynomials.(x+2)(2x² + 9x+8)OA. 16x³+72x² + 46x-16OB. 2x³ + 13x²2 - 26x+16OC. 2x³ +17x² +22x+16OD. 2x³ + 13x2+26x+16

Answer 1

Case: Polynomials

Method:

`\begin{gathered} (x+2)(2x^2+9x+8) \\ x(2x^2+9x+8)+2(2x^2+9x+8) \\ 2x^3+9x^2+8x+4x^2+18x+16 \\ 2x^3+9x^2+4x^2+8x+18x+16 \\ 2x^3+13x^2+26x+16 \end{gathered}`

Final answer:

`2x^(3)+13x^(2)+26x+16`
