Answer for a2 plus 28a plus 27?

Answer 1

a2 + 28a + 27

As it stands, there's no answer, because there's no question here.

The expression can be factored: (a+1) x (a+27) , but that's just a different way to write

the same expression, and there's still no question.

If we were told that some number is equal to this expression, then we could calculate

the value of 'a' that makes that a true statement.

For example, if this expression is 'zero', then ( a = -1 ) and ( a = -27 ) are both true.

But so far, there's no question asked, so there's no answer.
