Question

if a + b is equal to 8 and a b is equal to 1100 a square + a b + b square​

Answer 1

Given,

• a + b = 8
• ab = 1100
• Find : a²+ab+b²

According to condition,

(a + b)² = a² + 2ab + b²

(8)² = a² + b² + 2(1100)

64 = a² + b² + 2200

a² + b² = 64 - 2200

a² + b² = -2136

... a² + b² + 2ab

= -2136 + 2200

= 64. ...Ans

Answer 2

Answer:

(a+b)^2 = a^2+2 ab+b^2

8^2 =á^2+1 I00+1100+b^2

64-1100 = a^2+ab+b^2

á^2 + ab+b^2 =-1036
