Answer:
C
Step-by-step explanation:
The sum of the roots = - [tex]\frac{b}{a}[/tex]
that is x₁ + x₂ = - [tex]\frac{b}{a}[/tex]
x₁ = 2 and x₂ has to be found
Given
x² - 6x + 8 = 0
with a = 1, b = - 6, c = 8, then
2 + x₂ = - [tex]\frac{-6}{1}[/tex] = 6 ( subtract 2 from both sides )
x₂ = 4
The other solution is x = 4 → C
