Answer:
Option 1. 5 is the correct option.
Explanation:
Since we know the standard form of a polynomial is ax²+bx +c =0
So we have to transform the given equation 2x²-4x+6 =1 in the standard given as above.
2x² - 4x + 6 = 1
2x² - 4x + 6 - 1 = 0
2x² - 4x + 5 = 0
Now this is the standard form of the equation.
Here constant term c = 5.
Therefore Option 1. c = 5 is the correct option.
