What is the discriminant of x^2 + 3x + 1 = 0 ?

√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

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
