What is the coefficient of x2 in the expression 3x2 + 5x - 4?

  1. 3

  2. 4

  3. 5

In this case, the variable is x2. Therefore, the coefficient of x2 in the given expression is the number that is being multiplied by x2, which is 3. The other options, 4, 5, and 7, are all coefficients for different variables and do not pertain to x2 in the given expression.
