The general form of a quadratic equation is written as follows:

Ax^2 + Bx + C

Writing the given equation to the said form we do as follows:

 2x^2 - 4x + 6 - 1 = 1 - 1
 2x^2 - 4x + 6 - 1 = 1 - 1
 2x^2 - 4x + 5 = 0

Therefore, the value of C would be 5, first option.

Answer:

The value of c is 5.

Explanation:

The given equation is [tex]y=2x^2-4x+6=1[/tex]

General form of a quadratic equation is given by

[tex]y=ax^2+bx+c=0[/tex]

Subtract 1 to both sides of the given equation

[tex]y=2x^2-4x+6-1=0\\y=2x^2-4x+5=0[/tex]

Comparing with general equation, we get

a = 2

b = -4

c= 5

The value of c is 5
