Grade 11 Polynomials and Rational Expressions CCSS: HSN-CN.C.9

Jeremy is working with the Fundamental Theorem of Algebra, and thinks he's found an exception. Looking at [math]f(x) = 4(x-1)^2[/math], this will result in only one root, [math]x=1[/math]. Therefore, despite this being a second degree polynomial, there is only one root. Is this correct?
  1. Yes, this is a known exception.
  2. No, this is not a polynomial, it is a quadratic function.
  3. No, if the quadratic formula is used, the other root is found.
  4. No, this root has multiplicity of 2, which means it counts as two roots.
