5. Which of these equations shows prime factorization done correctly? 76 = 2 x 2 x 19
140 = 1 x 2 x 2 x 5 x 7
132 = 11 x 3 x 4
24 = 2 x 2 x 6

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.

x = -2

y = 848
