First steps with polynomials

The ____________ of a polynomial with only one variable is the largest exponent of that variable.

• constant

• degree

• variable

• coefficent

 $4xy^{-2}$  

• Polynomial

• Not a Polynomial

 $-6x^2+\left(\frac{8}{5}x\right)$  

• Polynomial

• Not a Polynomial

Polynomial comes from "poly" and "nomial" which means?

(a)  

Add or Subtract to Simplify:
(4x²+ x) - (x²+ 2x)

• 3x² - x
• 4x² + 2x
• 3x² + 3x
• 3x² + 2x

Subtract the polynomials.

(2x + 5y) - (3x - 2y)

• -x + 3y

• -x + 7y

• 5x + 7y

• 7xy + 1xy

(3x + 4y - 3z) - (2x - 6y + 7z)

• x + 10y - 10z
• -x +10y - 10z
• x -10y - 10z
• -x -10y - 10z

Find the difference. 
(3- 2x + 2x²) - (4x -5 +3x²)

• x_² + 6x + 8
• 2x² + 5x - 7
• -x² -6x + 8
• -2x² + 11x - 4

Add or Subtract to Simplify:
(5x + x² - 4) - (4x - x² + 6)

• 2x² + x + 2 
• x + 2
• 2x² + x - 10 
• x - 10 

Add or Subtract to Simplify:

(4x²+ x) - (x² -2x)

• 3x² - x

• 4x² + 2x

• 3x² + 3x

• 3x² + 2x
