What should be added in 16a2 +2 ab to make perfect square

Answer»

Answer:

6ab+ b²

Step-by-step explanation:

16a²+2ab

if we have to make it a perfect SQUARE then the FORM will be...

(4a)²+2.4a.b+(b)²

= 16a²+8ab+b²

so the extra parts that we have to INCLUDE to make it a perfect square are...

(16a²+8ab+b²) - ( 16a²+2ab)

= 6ab + b²

hope it helps...
