How many real solutions are there?

The discriminant is:

So which means there are two distinct real solutions.

Hope this helps.

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

square root

step-by-step explanation:

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
