Question

Please help me with the above question!

Answer 1

Given :-

• a + b = 12
• ab = 14

To find

• a² + b²

Formula Implemented:-

• ( a + b)² = a² + b² + 2ab

Lets do !

(a + b)² = a² + b² + 2ab

(12)² = a² + b² + 2 (14)

144 = a² + b² +28

144 -28 = a² + b²

116 = a² + b²

a² + b² = 116

Option b

____________________________

Know more :-

(a+ b)² = a² + b² + 2ab

( a - b )² = a² + b² - 2ab

( a + b )² + ( a - b)² = 2a² + 2b²

( a + b )² - ( a - b)² = 4ab

( a + b + c )² = a² + b² + c² + 2ab + 2bc + 2ca

a² + b² = ( a + b)² - 2ab

(a + b )³ = a³ + b³ + 3ab ( a + b)

( a - b)³ = a³ - b³ - 3ab ( a - b)

If a + b + c = 0 then a³ + b³ + c³ = 3abc
