Question

दो पूर्णांक
a तथा b ऐसे ज्ञात कीजिए कि
(i) a+ b = 8 और ab = 15​

Answer 1

Answer:

a = 5

b= 3

Step-by-step explanation:

(a-b)² = a²+b²-2ab

(a-b)² = (a+b)²- 4ab

(a-b)² = 64 - 4×15

(a-b)² = 64-60

(a-b)² = 4

a-b = √4

a-b= 2

a-b=2

a+b=8

2a = 10

a = 5

a+b = 8

so , 5+b=8

b= 8-5

b = 3
