1.	The formula used in the product of 1962 is ………………….. A) (a + b)2 B) (a – b)2 C) a2 – b D) a – b2
Answer» Correct option is B) (a – b)² Correct option is (B) (a – b)² \(196^2=(200-4)^2,\) Let a = 200, b = 4. Then formula use in the product of \(196^2\) is \((a-b)^2.\)

The formula used in the product of 1962 is ………………….. A) (a + b)2 B) (a – b)2 C) a2 – b D) a – b2

Answer»

Correct option is B) (a – b)²

Correct option is (B) (a – b)²

\(196^2=(200-4)^2,\)

Let a = 200, b = 4.
