Given the equation:
22 - 10x - 20
Determine the number to be added in order to complete the square.
Explanation:
There is no possible way in order to complete the square, since x^2 cannot be added in the equation. It is a common rule in quadratic equations, as well as cubic equations and quartic equations that you cannot add a term with a degree, only constants. Hence, what we can only do to the equation, is to combine similar terms which is 22 and -20.
Solution:
22 - 10x - 20
2 - 10x
Final answer:
It is not possible to complete the square.
