B Correct answer
Explanation

Standard quadratic form is ax^2 + bx + c = 0. Comparing 2x^2 - 4x + 6 = 0, we identify a=2, b=-4, c=6.

AI explanation

The standard form of a quadratic equation is a x squared + b x + c = 0. Comparing the given equation 2 x squared minus 4 x plus 6 equals 0 to this form, the coefficient of x is the value of b. Therefore, b equals -4.
