Which of the following correctly shows the quadratic formula for the given equation? 3x2 - 6x + 8 = 0

The quadratic formula is expressed as:

x = (-b +/- √(b^2 - 4ac) ) / 2a

where a, b and c are the coefficients of the quadratic equation with the form ax^2 + bx + c=0

Therefore, the quadratic equation would be:

a = 3
b = -6
c = 8

x = (-(-6) +/- √((-6)^2 - 4(3)(8) ) / 2(3)

Hope this helps.
