Question

How many real solutions are there?

Answer 1

The discriminant is:

`D=4^2-4(1)(2)=8`

So
`D>0` which means there are two distinct real solutions.

Hope this helps.

Answer 2

2 real solutions

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
