Question

What is the quotient (x 4 + 10 x3 + 21 x 2 + 6x - 8 ÷ (x + 2)?

Answer 1

Answer B. x3+ 8x2 + 5x - 4

Answer 2

We need to calculate the division between two polynomials:

`\begin{gathered} (x^4+10x^3+21x^2+6x-8)/(x+2)=x^3+8x^2+5x-4 \\ x^4+10x^3+21x^2+6x-8=(x+2)(x^3+8x^2+5x-4) \end{gathered}`

The option B is the correct answer.
