I'm assuming you're doing solve the square right now, so you should be able to do the rest.
Answer:
Step-by-step explanation:
We have been given an expression . We are asked to complete the square to make a perfect square trinomial. Then, write the result as a binomial squared.
We know that a perfect square trinomial is in form .
To convert our given expression into perfect square trinomial, we need to add and subtract from our given expression.
We can see that value of b is 11, so we need to add and subtract to our expression as:
Upon comparing our expression with , we can see that , and .
Upon simplifying our expression, we will get:
Therefore, our perfect square would be .
