Question

If x is a natural number. what number is to be added to x²+6x to get a perfect square​...

Answer 1

Answer:

9

Step-by-step explanation:

(a ± b)² = a² ± 2ab + b²  

x² + 2 × 3 × x + 3² = (x + 3)² , so we have to add 9

Answer 2

We should add half the square of 6 to get a perfect square.

x²+6x+3²=(x+3)²
