Answer 2

To identify the type and number of solutions to a quadratic equation, find its discriminant, which is given by the formula \[D = b^2 - 4ac\]for this equation\[D=1^2-4(4)(-1)=1+16=17\]When D is equal to a positive real number which is not a perfect square, as it is in this case, there are two real and irrational solutions to the quadratic equation.

So 2 is the answer
