Question

What is the value of the discriminant in the equation shown below?
x^2+3x-6=0

Answer 1

Do you have an answer already?

Answer 2

how is the discriminant defined?

Answer 3

Given:\[ax^2 + bx + c = 0\]The descriminant is:
\[b^2 - 4(a)(c)\]

So what do you have for this equation?

Answer 4

given this explanation of the discriminant; what do you say a,b and c are equal to?

Answer 5

so it would be 3\[3x^2\]-4(1)(6)

Answer 6

the descriminant doesn't include the variables.

Answer 7

i mean no x

Answer 8

close; you dropped the "-" off the 6 tho

Answer 9

3^2 - 4(1)(-6)

Note that the 6 is negative because it's -6 in the above equation.

Answer 10

[a] x^2 [+b] x [+c] = 0
[1] x^2 [+3] x [-6] = 0

Answer 11

so the answer is -15?

Answer 12

9 - 4(1)(-6)
= 9 - (-24)
...
\(\ne-15\)

Answer 13

Nope.

Answer 14

oh so 33

Answer 15

Correct

Answer 16

yay
