What is the value of 8x + 4x2 when x = -2?

  1. -16

  2. 12

  3. 32

  4. -12

The correct answer is: -12

When substituting -2 for x, the equation becomes 8(-2) + 4(-2)^2. Simplifying this, we get -16 + 4(4) = -16 + 16 = 0. Therefore, none of the given choices are correct. Option D is the closest answer, with a value of -12, but it is still not accurate. It is important to pay attention to the signs and to properly calculate exponents when solving equations.
