Question

Given the trinomial 2x2 + 4x - 2, what is the value of the discriminant?

0

10

32

36

Answer 1

2x^2+4x-2

Answer 2

for a quadratic in the form

\[ax^2 + bx + c\]

the discriminant is

\[\Delta = b^2 - 4ac\]

in your question a = 2, b = 4 and c = -2

just substitute and calculate it

Answer 3

The formula for the discriminant is b^2 - 4ac. Plug in the values from you polynomial and do the math. Your discriminant would be (4)^2 - 4(2)(-2). What does that come to?
