As the expression is given by

To determine

Simplify the expression

The given expression is very easy to simplify. All we need is to subtract 9 from 89 and we will get the required answer.

i.e.

89 - 9

subtract the numbers: 89 - 9 = 90

⇒ 89 - 9 = 80

Therefore, we conclude that:

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
