1. Perform the indicated operations, and then answer the question. (a) (-6) (-2)
(b) (-6) (2)
(c) A product has five factors. Three factors are negative integers and two factors are positive integers. Do you know the sign of the product? Explain.

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.

i belive those are the ones that are under 90 degreese.
