Randy divides (2x4 – 3x3 – 3x2 + 7x – 3) by (x2 – 2x + 1) as shown below. What error does Randy make?

He makes a subtraction error.

He makes an error writing the constant term in the quotient.

He makes an error choosing the x-term in the quotient.

He makes an error rewriting the problem in long division.

Which expression is equivalent to ?

Option

One root of is x = 2. What are all the roots of the function? Use the Remainder Theorem.

x = 2, x = 3, or x = 4

x = –2, x = –3, or x = –4

x = 1, x = 2, x = 3, or x = 13

x = –1, x = –2, x = –3, or x = –13
