Which expression is equivalent to 9(x – 4) – 6x?

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

center= (-2,0)

radius= sqrt2/2
