For the quadratic equation x2 + 2x + 8 = 0, find the value of the discriminant. Then, describe the number and type of roots for
stepladder [879]

ax^2 +bx+c=0
X^2 + 2x+8=0 so a=1, b=2, c=8

Discriminat= b^2 -4ac=2^2 -4•1•8=4-32=-28

So there are no real number solutions, yet there are complex numbers solutions.

Solutions=(-b+- sqrt (discriminant))/2•a
=(-2+-i sqrt ( 2•2•7))/2
Solutia 1= -1 + i sqrt7
Solutia 2= -1 - i sqrt 7
