What is the coefficient of the term x5y7 in the expansion of (x - y)12 ?

12 and -12

Step-by-step explanation:

12x-12y is the expansion using the distributive property, so the coefficient of x is 12 and the coefficient of y is -12

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.
