Answer:

C

Step-by-step explanation:

The sum of the roots = - \frac{b}{a}

that is x₁ + x₂ = - \frac{b}{a}

x₁ = 2 and x₂ has to be found

Given

x² - 6x + 8 = 0

with a = 1, b = - 6, c = 8, then

2 + x₂ = - \frac{-6}{1} = 6 ( subtract 2 from both sides )

x₂ = 4

The other solution is x = 4 → C

Step-by-step explanation:

x2 - 6x + 8 = 0

x2 - 4x - 2x + 8 = 0

x(x - 4) - 2(x - 4) = 0

(x-4)(x-2) =0

x-4 = 0. x-2 = 0

x = 4. x = 2

Option C is the correct answer

Answer:

Your answer is A.

Step-by-step explanation:

Looking at the graphing two-equation: y = x^3 -3 and y = x^2+6 are up there, it can help us determine the limit of domain.

The dot is the x<=2 for equation y=x^3-3.

The circle is x>2 for equation y=x^2+6

Useing reason, and logic, my guess would be if you take 125, and divided it by 4, you would get 31.25. that should be the answer... if i am wrong, i am truely sorry. I havent been in the subject in a while...
