How many real solutions are there?

The discriminant is:
[tex]D=4^2-4(1)(2)=8[/tex]
So [tex]D>0[/tex] which means there are two distinct real solutions.
Hope this helps.
Answer:
2 real solutions
Step-by-step explanation:
x^2 +4x+2 =0
This is in the form ax^2 + bx +c
The discriminant is
b^2 -4ac
4^2 - 4*1*2
16 - 8
8
Since this is greater than 0, we have 2 real solutions
