Question

Use b^2-4ac find its value given the following quadratic equation:

2x2 + 7x + 3 = 0

Answer 1

a = 2
b = 7
c = 3

Now insert the values in:
b^2-4ac

Answer 2

i did but i got 24= 0?

Answer 3

actually i got 25= 0

Answer 4

I keep getting diffrent numbers for my answer like73 and 13?

Answer 5

49 - 4(2)(3)
49 - 24

25

Answer 6

lol, 25 is the right answer.

Answer 7

b^2-4ac
a=2
b=7
c=3

7^2-4(2)(3)=
49-24=
25

Answer 8

lol cool so i got it right the first time does it matter that 25=0?

Answer 9

Lol, congrats..

yes it does.

Answer 10

wait what do u mean 25=0?

Answer 11

u dont have to write the answer that way..

Answer 12

like 25 = 0

Answer 13

With the equation , but the problem is still correct?

Answer 14

no 25 does not equal zero. the formula is
\[x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\]

Answer 15

the answer will be just 25.

Answer 16

no the answer will not be 25

Answer 17

o.O

Answer 18

the answer will be
\[\frac{-7\pm\sqrt{25}}{4}\]

Answer 19

she wants the discriminent.

Answer 20

he's right the answer isnt 25 cuz u ddnt use the whole quadratic equation

Answer 21

no it says solve using discriminant

Answer 22

no she wants the answer which is y its set equal to 0 but she ddnt put the whole formula down

Answer 23

-_-
Confused.

Answer 24

u have to use the discriminant to find the x values that solve the equation like satellite said

Answer 25

\[b^2-4ac=25\] and the solutions to \[2x^2 + 7x + 3 = 0\]using that in the formula are
\[\{-\frac{1}{2},-3\}\]

Answer 26

in other words we have to use quadratic formula!

Answer 27

yup but written in a confusing way

Answer 28

Leave it..

Answer 29

Lol.

Answer 30

....okay all of that was a cunfusing way of telling me that 25 is correct????

Answer 31

i will go with 25, rest go with satellite's answer.

Answer 32

the answer the way u aske it is 25 because u asked for the discriminant. but what exactly did u mean 25=0?

Answer 33

just i didnt know if you used the equation at the top or not
