Answer:

if the discriminant < 0 no solution

if = 0 then one solution

if > 0 then two solutions

start from the first one and calculate b^2-4ac

the first one is x^2 + 4x +4 = 0

a is the factor next to x^2 (1 in this case)

b is the factor next to x (4 in this case)

c is the number without any x (4 in this case)

so the discriminant is 4^2 - 4*(1)*4 = 16-16 = 0 = one solution
