Question

IF a-b=7 and a²+6²=53. Find ab​

Answer 1

Answer :

ab = 2

Solution :

Given,

a - b = 7

a² + b² = 53

We know that,

(a - b)² = a² + b² - 2ab

7² = 53 - 2ab

2ab = 53 - 49

ab = 4/2

ab = 2

Answer 2

Answer:

a-b=7-----------(1)

a^2+6^2=53–---------(2)

using 2

a^2=53-36

a^2=17

a=√17

b=√17-7
