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

the discriminate can be found from the quadratic equation x= -b √(b)^2 -4ac all over 2a

Step-by-step explanation:

1) 2x^2 +4x-2

a=2

b=4

c= -2

2) discriminant= b^2 -4ac

(4)^2 -4(2)(-2)

16-4-4

discriminant= 16

hope I got this right!

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
