Long division of polynomials

Solve using long division.  $\left(x^2+2x\ -\ 63\right)\div\left(x+9\right)$  

•  $x-7$  

•  $x^2-7$  

•  $x+7$  

•  $x^2+3x-54$  

Is this division problem worked correctly?

• This is correct!

• This is incorrect, and error occurs on the 2nd line!

• This is incorrect, and the error occurs on the 4th line!

• This is incorrect, and the error occurs on the 3rd line!

Which term must be inserted in the dividend before you begin long division?

 $\left(2x^3+5x^2+9\right)\div\left(x+3\right)$  

•  $0x^4$  

•  $0x^3$  

•  $0x^2$  

•  $0x$  

What is the remainder when you divide
 $\left(2x^3-5x-7\right)\ by\ \left(x+2\right)$  ?

• -9

• 11

• -13

• -1

What do you call the number that you divide by?

• Quotient
• Divisor
• Remainder
• Factor

The answer to a division question is called the. . .

• Quotient

• Sum

Which term is missing in this problem?

(2x³ + 5x² + 9 )÷

(x + 3)

• x⁴

• x³

• x²

• x

(2x³ - 5x² + 3x + 7) ÷ (x - 2)

• 2x³ - x² + x + 9

• 2x² - x + 1

• $2x^2-x+1+\frac{9}{x-2}$

• $2x^2-9x-15-\frac{23}{x-2}$

Find the Quotient
(2x³ - 5x² - 3x + 7) / (x - 2)

• 2x²- 9x +15
• 2x² - x - 5
• 2x² - 9x - 21
• 2x² + x + 5
