Step-by-step explanation:

Evaluate: (5 + 2)^2 - 49 + 3 = ?

=> (5 + 2)^2 - 49 + 3. [∵(a+b)² = a²+2ab+b²]

=> (5)^2 + 2(5)(2) + (2)^2 - 49 + 3

=> 25 + 2(10) + 4 - 49 + 3

=> 25 + 20 + 4 - 49 + 3

=> 45 + 4 - 49 + 3

=> 49 - 49 + 3

=> 52 - 49

=> 3 Ans.

Used formulae:

  • (a+b)² = a^2 + 2ab + b^2
