What is the discriminant of the quadratic equation 0 = -x2 + 4x - 2?

8

Step-by-step explanation:

-x²+ 4x - 2 = 0

x² - 4x + 2 = 0

where

a = 1

b = -4

c = 2

Now,

Diacriminant (D)

D = b² - 4ac

= (-4)² - 4(1)*(2)

= 16 - 8

= 8

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
