The top number in a fraction. Shows how many parts we have. (The bottom number is the Denominator and shows how many equal parts the item is divided into.)
For this case what you can do is factorize the <span>polynomial equation</span>, which would be left like follows x ^ 3 + x ^ 2 + 9x + 9 = 0 (x + 1) (x ^ 2 + 9) = 0 Resolving, we have that the missing root is x = -1 Answer x=-1
