Question

a²+b²=100 and ab =48 a+b=? please answer in copy ​

Answer 1

Answer:

Step-by-step explanation:

a2 + b2 = (a+b)2- 2ab

So, (a+b)2= 100+2ab= 100+2*48

So (a+b)2= 196

So a+b = √196 =14

Answer 2

Answer:

Question

a²+b²=100 and ab =48 a+b=? please answer in copy

Solution

<By using identity - (a+b)² = a²+b² + 2ab>

(a+b)² = a²+b² + 2ab

On putting the value of a²+b²=100 and ab =48

(a+b)² = 100 + 2×48

(a+b)² = 196

(a+b)² = 196

(a+b) = 14
