Question

Given the trinomial 2x^2 + 4x + 4, predict the type of solutions.

Two rational solutions
One rational solution
Two irrational solutions
Two complex solutions

Answer 1

Take the discriminate \[
b^2-4ac = (4)^2-4(2)(4) = 16-32 = -16
\]The discriminate tells us about the solutions.

Answer 2

Negative discriminant tells us we have complex solutions

Answer 3

it says "solutions" but only allows me to choose 1

Answer 4

so that means d is eliminated?

Answer 5

i meant does that mean that D is the answer
