We are asked to find the "product" of the two numbers, " 12 " and " -5 " .
________________________________________________________
The "product" refers to the result of "multiplying" numbers.
________________________________________________________
So, what is the value, when "12" is multiplied by "-5" ?
________________________________________________________
<u>Note</u>: When a "positive number" is multiplied by a "negative number" , the result is a "negative number" .
________________________________________________________
So; the product of "12" and "-15" is: " 12 * -5 " ; which equals: " -60 " ;
which is: Answer choice: [A]: " - 60 " .

Answer:

Step-by-step explanation:
Take out 4:
4(x^2-8x)-12
=4(x^2-8x+16-16)-12
=4(x^2-8x+16)-64-12
=4(x^2-4)^2 - 76
=
The fundamental theorem of algebra states that a polynomial of degree has exactly n roots (including complex and multiple).
The degree of a polynomial is the highest (non-negative) exponent of the polynomial, in this case is 17 from the term 15x^17.
