Use the quadratic equation 4x2+4x+1=0 to answer the questions.

a: what are the solutions to the quadratic equation?
b: which statements accurately interpret the meanings of the solutions?
select one answer for question a, and select two answers for question b.

a: x=−12 or x=12
a: x=−12
a: x=2 or x=−2
b: since the quadratic equation has one real solution, the graph of the quadratic equation intercepts the x-axis at (−12,0).
b: since the quadratic equation has two real solutions, the graph of the quadratic equation intercepts the x-axis at (−12,0) and (12,0).
b: since the solutions are x=−12 or x=12, two factors of the quadratic expression 4x2+4x+1 are (2x+1) and (2x−1).
b: since the solution is x=−12, two factors of the quadratic expression 4x2+4x+1 are (2x+1) and (2x+1).
b: since the solutions are x=2 or x=−2, two factors of the quadratic expression 4x2+4x+1 are (x−2) and (x+2).
b: since the quadratic equation has two real solutions, the graph of the quadratic equation intercepts the x-axis at (−2,0) and (2,0).
