Question

find a²+b², if a-b=19 and ab=8​

Answer 1

Answer:

To find , a² + b²

If , (a - b) = 19 and ab = 8

So As we know

(a - b)² = a² + b² - 2ab

= (a - b)² + 2ab = a² + b²

Now putting the value as it is given that (a-b) = 19 and ab = 8

So , a² + b² = (a - b)² + 2ab

a² + b² = (19)² + 2 × 8

a² + b² = 361 + 16

a² + b² = 377.
