Replace ∗ with a monomial so that the trinomial may be represented by a square of a binomial: b2 + 20b +*

Given:

The expression is:

To find:

The a monomial so that the trinomial may be represented by a square of a binomial.

Solution:

If an expression is , then be need to add square of half of coefficient of x, i.e., in the given expression to make in perfect square.

We have,

Here, coefficient of b is 20,so wee need to add square of half of coefficient of b, i.e., .

Therefore, we need to add 100 to make a perfect square binomial.
