Given the equation 2x2 – 16x + 32 = 0, what is the value of x?

–8
–4
4
8

The correct answer is: 8

In this equation, we can see that the coefficients are small and relatively easy to work with. To solve for x, we can use the quadratic formula x = (-b ± √(b^2 - 4ac))/2a. Plugging in the values from the given equation, we get x = (16 ± √(256 - 128))/4. Simplifying further, we get x = (16 ± 8)/4. This gives us two possible values for x: x = 6 or x = 2. Therefore, options A, B, and C are incorrect. Option D, 8, is the correct answer because it is one of the possible solutions for x.
