1.	The formula involved in the product of 302 × 298 A) (a + b)2 B) (a – b)2 C) (a + b) (a – b) D) None
Answer» C) (a + b) (a – b) Correct option is (C) (a + b) (a – b) \(302\times298\) = (300+2) (300-2) Let a = 300 & b = 2 \(\therefore\) Formula involved in the product of \(302\times298\) is (a+b) (a–b).

Answer»

C) (a + b) (a – b)

Correct option is (C) (a + b) (a – b)

\(302\times298\) = (300+2) (300-2)

Let a = 300 & b = 2

\(\therefore\) Formula involved in the product of \(302\times298\) is (a+b) (a–b).
