What is the standard form for a Polynomial?

• Degrees must drop from left to right. Like terms must be combined.

• Degrees drop from right to left. Like terms do not have to be combined.

• 3x⁸+ 4x⁵

• 3x²+3x³

What is a leading coefficient?

• The coefficient that is non-existent.

• The coefficient of the term with the lowest degree.

• The coefficient of the term with the highest degree.

How do you subtract polynomials?

• Distribute -1 throughout. Then continue with the same procedure for adding.

• (3y-4y)

• Distribute 1 thoughout. Then do same procedure for substraction.

• None of the above.
