Discriminant = -24
No real roots.
Step-by-step explanation:
x^2 + 2x + 7 = 0
The discriminant = b^2 - 4ac
= 2^2 - 4*1*7
= -24
So there are no real roots.
Answer:
Let the numbers are
x, (x+2), (x-2) and (x+4)
Step-by-step explanation:
x + x +2 +x - 2+x+4 = 80
4x +4 = 80
4x =80-44x = 76
4x = 76
x = 76/4
x = 19x
x=19
(x+2) =19+2=21
(x-2) = 19-2=17
(x+4)=(19+4)=23
