D Correct answer
Explanation

The standard quadratic equation is ax^2 + bx + c = 0. Rearranging 4x^2 - 6x = 64 gives 4x^2 - 6x - 64 = 0. Comparing this to the standard form, c = -64.

AI explanation

To compare the equation 4 x squared minus 6 x equals 64 with the standard quadratic form a x squared plus b x plus c equals 0, first move all terms to the left side. This results in 4 x squared minus 6 x minus 64 equals 0. In this standard form, the constant term c is -64.
