What term should be added to expression to make it a perfect square ​

Answer»

in this term we can see

49a⁴ + 50a²b² + 16b⁴

= (7a²)²+(4b²)² + 50a²b² ....(1)

We can MAKE this term as a PERFECT square of

(7a²+4b²)²

= 49a⁴+ 16b⁴+ 56a²b² ...(2)

From (1) and (2) we can see that

to make 49a⁴ + 50a²b² + 16b⁴ a perfect square [= (7a²+4b²)²] we MUST add 6a²b² to it
