How can you describe the solution set of the equation 16x2 - 8x + 1 = 0?
a: there are two different real solutions because the expression has two different factors.
b: there are two different real solutions because the expression has three terms.
c: there is one real solution because the expression’s factors are the same.
d: there are no real solutions because the expression cannot be factored.
