Question

medal+Fanning
Decide which part of the quadratic formula tells you whether the quadratic equation can be solved by factoring.

−b b2 − 4ac 2a

Use the part of the quadratic formula that you chose above and find its value given the following quadratic equation:

2x2 + 7x + 3 = 0

Answer 1

This question has to do with the discriminant of a quadratic equation. That becomes a concern when solving a quadratic equation using the Quadratic Formula.

Attached for three items for you to study later.

The discriminant is called the discriminant because it discriminates among the types of roots a quadratic has. You can predict the type roots based on the discriminant.

Answer 2

Thank you and i need a numeric answer

Answer 3

@HelloGoodmorning

I get that you need an answer but I thought you might want to know something about how to get the answer for later.

If you looked at the attachments, you might know the answer to your first question. Do you know? If so, post that, and then we'll move to the second part.

Decide which part of the quadratic formula tells you whether the quadratic equation can be solved by factoring.

Answer 4

Which one of these three: −b b2 − 4ac 2a

Answer 5

Loll I'm trying to check it out but my laptop is so slow that i'm unable to

Answer 6

and what do you mean by which one of these three

Answer 7

You wrote the question yourself with these three choices:

Decide which part of the quadratic formula tells you whether the quadratic equation can be solved by factoring.

−b b2 − 4ac 2a

Answer 8

These are the three choices: Decide which part of the quadratic formula tells you whether the quadratic equation can be solved by factoring.

−b b2 − 4ac 2a

Answer 9

Loll I'm trying to check it out but my laptop is so slow that i'm unable to

Answer 10

This option should read: b² − 4ac

Answer 11

Ok

Answer 12

Now just plug in the numbers where the letters are. :)

Answer 13

2 x2 + 7x + 3 = 0

a = 2, b = 7, and c = 3

b² − 4ac = (7)² - 4 (2)(3) = ? @HelloGoodmorning

Answer 14

I'm easily confused I have adhd so sorry @Directrix

Answer 15

Give me a minute ill answer that

Answer 16

No rush at all. Take your time.

Your task is to crank out the value of this expression:

(7)² - 4 (2)(3)


So multiply 7 times 7.

Multiply 4 times 2 times 3.

Then, subtract what you got for (4 times 2 times 3) from what you got for (7 times 7).

Answer 17

Oh

Answer 18

7*7=49
4*2=8 and 8*3 equals =24 so 49-24=25

Answer 19

So the numerical answer is 25?

Answer 20

@Directrix

Answer 21

Correct.

Answer 22

Yes! All I have to put in is 25

Numerical Answers Expected!

Answer for Blank 1: 25

Answer 23

Answer for blank 1: b² − 4ac

Answer for blank 2: 25

Answer 24

@HelloGoodmorning

Answer 25

Wait a minute. How many blanks do you have for filling in. If there is only one and it is numerical, then it is the 25.----> as you said.

Answer 26

Loll yes there's only one blank

Answer 27

Put 25 in it and call it good.

Answer 28

Ok thank you

Answer 29

One question
How can you tell when a quadratic equation has two identical, rational solutions?
(choices)
a. when the radicand is negative
b. when b in the quadratic formula is greater than the radicand
c. when the radicand equals zero
d. when the radicand is not a perfect square

Answer 30

You are welcome.

Answer 31

I think the answer is c am I correct?

Answer 32

Your right I'm sorry

Answer 33

>> I think the answer is c am I correct?

Yes.
