The locations of three ships are represented on a coordinate grid but the following points: p(-2,5) q(-7 -5) and r(2 -3). which ships are farthest apart

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.
