Question

DatGuy! Sekkrit! Wishing! Anyone? Find the discriminant of 3x²+5x-2 = 0

Answer 1

49

Explanation:

`3x^2+5x-2 = 0`

Apply discriminant formula :
`D = b^2- 4ac`

`D=discriminant\\b=5\\a=3\\c=-2`

`D = b^2- 4ac`

Plug in the values for a, b, and c.

`D = 5^2- 4(3)(-2)`

Evaluate.

`D = 25- 12(-2)`

`D = 25- - 24`

`D=25+24`

`D=49`

Answer 2

49

Explanation:

3x²+5x-2 = 0

This is in the form

ax^2 + bx + c=0

a=3 b=5 c = -2

The discriminant is

b^2 -4ac

5^2 -4(3) (-2)

25 + 24

49

The discriminant is 49
