What is the coefficient of x2 in the equation 9x2 + 28x + 8?

The correct answer is: 9

The coefficient of x2 in this equation is 9. This is because the number in front of x2 represents the coefficient, which is the number multiplied by a variable. In this case, 9 is the only number that is directly multiplied by x2, so it is the coefficient for that term. Option A, 8, is the constant term in the equation, which means it is not multiplied by any variable. Option C, 28, is the coefficient of x, not x2. Similar to the explanation for the coefficient of x2, the coefficient of x is the number directly multiplied by x in the equation. Option D, 36, is not a term in the equation and therefore cannot be the coefficient for x2. It is possible that this number is obtained by simplifying or manipulating the given equation, but it is not the coefficient for
