Question

What should be added 16 a square + 8 a b to make it a perfect square

Answer 1

Answer:

b²

Step-by-step explanation:

We are given with 16a² + 8ab

Now, We know that (x + y)² = x²+2xy+y²

So, in this way

16a² can be written as (4a)²

8ab is written as 2(4a)(b) as first term is 4a

Hence, clearly from the formula b² will be the third term

To make a perfect square, we must add b²

Hence, 16a²+8ab+b² = (4a+b)²
