Answer 2

Step-by-step explanation:

Heya !!

Given :-

• a + b = 5
• a - b = 3

To Find :-

• find the value of 8ab(a^2+b^2)

Solution :-

a + b = 5 ........... equ ( 1 )

a - b = 3 ............ equ ( 2 )

solve equ ( 1 )

a + b = 5

a = 5 - b .........equ ( 3 )

putting equ ( 3 ) from equ ( 2 )

a - b = 3

5 - b - b = 5

-2b = 5 - 5

-2 b = 0

b = 2

putting value of b from equ ( 1 )

a + b = 5

a + 2 = 5

a = 5 - 2

a = 3

8 ab ( a^2 + b^2 )

8 × 3 × 2 ( 3^2 + 2^2 )

48 ( 9 + 4 )

48 ( 13 )

624

Hence the values is 624
