Use the quadratic polynomial x2+4x+4 to answer the questions.

a: which summary correctly applies the fundamental theorem to the quadratic polynomial?

b: which statement correctly verifies the application of the fundamental theorem of algebra?

select one answer for question a, and select one answer for question b.

a: this polynomial has a degree of 2, so the equation x2+4x+4=0 has exactly two roots.
a: this polynomial has a degree of 2, so the equation x2+4x+4=0 has two or fewer roots.
a: this polynomial has a degree of 2, so the equation x2+4x+4=0 has more than two roots.
b: the quadratic equation x2+4x+4=0 has two real solutions, x=−2 or x=2, and therefore has two real roots.
b: the quadratic equation x2+4x+4=0 has one real solution, x=−2, and therefore has one real root with a multiplicity of 2.
b: the quadratic equation x2+4x+4=0 has three real solutions, x=2, x=−2, and x=0, and therefore has three real roots.
