Answer:
p-q= -4
p=q-4
x^2 + px + q=0
=> x^2 + (q-4)x + q = 0
d= b^2-4ac
=(q-4)^2 - 4(1)(q)
= q^2 + 16 -8q - 4q
=q^2 -12q+16
given that D=16
q^2 -12q+16 = 16
=> q^2 -12q = 0
=> q^2 = 12q
=> q = 12q/q
=> q= 12
Therefore the value of q is 12 and the value of p is q-4 = 12-4= 8

Answer:
$440
Step-by-step explanation:
Interest=Principal × Rate × Time/100(Formula)
We have to find the Interest.
Interest = $2000× 5.5 × 4/100
100 Interest = 44000
Interest = 44000/100
Interest = $440(Answer)
