Answer:√5

Step-by-step explanation:

x^2 + 3x + 1 = 0

Yo find discriminant

The discriminant helps us to determine the number of solutions to a quadratic equation

The general formula for solving quadratic equation is

x = -b+-(√b^2 -4ac)/2a

(√b^2 -4ac) gives the determinant

From the equation, a =1 (the coefficient of x^2

b = 3, the coefficient of x

c = 1, the constant

√b^2 -4ac =√3^2- 4×1×1

=√5
