The sum of the zeroes of the polynomial 2x² - 8x + 6 is:

Given polynomial is, 2x² - 8x + 6=0 .
Now, the general equation is

{ax}^{2} + bx + c = 0

.
Comparing (1) with the general equation,
a=2
b=-8
c=0
Let α and β are the two zeroes of the quadratic polynomial.

Sum of zeroes (α + β) = − b a ⇒ a + β = − (− 8) 2 ⇒ α + β = 82 ⇒ α + β = 4

Sum of zeroes = 4
Hence, the sum of the zeroes of the polynomial 2x² - 8x + 6 is 4.
Therefore, option 4 is correct.
