JUST CHECKING IF IM CORRECT, IF IM WRONG PLEASE HELP, I THINK I UNDERSTAND IT BUT JUST LEARNING IT. if you have any tips of understanding trinomials please say. Given the trinomial 2x2 + 4x + 4, predict the type of solutions. (2 points) Two rational solutions One rational solution Two irrational solutions Two complex solutions<---

Directrix (directrix):

2x2 + 4x + 4 does not have solutions. 2x2 + 4x + 4 = 0 does.

Do you know how to find the discriminant of the polynomial equation? Or, you could use the Quadratic Formula to get the roots.

OpenStudy (anonymous):

a = 2 b = 4 c = 4 Use the discriminant. sqrt(b^2-4ac) sqrt(4^2-4(2)(4)) sqrt(16-32) So you have the square root of a negative number

Directrix (directrix):

Which means this as you have marked: Two complex solutions<---
