Question

given the trinomial 2x^2 + 4x + 4 predict the type of solutions

Answer 1

@Becki Hey !!

Answer 2

imaginary numbers

Answer 3

It says 2 rational numbers, 1 national number 2 irrational and 1 irrational

Answer 4

Answer 5

Hm. Well, it can't factor, so you have to use the quadratic formula. Doing this gives you sqrt (-1) both answers, so I'm not sure what your answer would be. The i isn't rational or irrational...

Answer 6

oh one of the anwers is 2 complex solutions

Answer 7

@Sephora

Answer 8

Its your homework right

Answer 9

you expect us to do it for you by saying predict the solution

Answer 10

Yea.but I want to understand it so I can do the rest!

Answer 11

you wont understand it if a you and a person do it step by step>DUH!

Answer 12

Naww really? @Sephora

Answer 23

@crystelle Find the discriminant of the quadratic equation.

See attachment.

Answer 24

The discriminant will tell what to expect in terms of the nature of the roots. But, find it first.

Answer 25

hey i don't know if you are done with this question, but
any time you have a square like x^2, there will always be 2 possible solutions.
using the quadratic equation

when the stuff under the square root (stuff actually being call the discriminate) then the following can be determined for the types of answers, or in other words the types of roots

if
b^2 - 4ac > 0 then the roots (answers) are real numbers and not equal to each other
b^2 - 4ac = 0 then the roots (answers) are real numbers and equal to each other
b^2 - 4ac < 0 then the roots (answers) are complex numbers and not equal to each other
