The formula used in the product of 96 × 104 is ………………. A

1.	The formula used in the product of 96 × 104 is ………………. A) (a + b) (a – b) B)(a – b)2 C) (a – b)2 D) a2 – b
Answer» A) (a + b) (a – b) Correct option is (A) (a + b) (a – b) \(96\times104\) = (100 - 4) \(\times\) (100 + 4) Let a = 100, b = 4 Then \(96\times104\) = (a - b) (a + b) \(\therefore\) Formula used in product of \(96\times104\) is (a + b) (a – b).

The formula used in the product of 96 × 104 is ………………. A) (a + b) (a – b) B)(a – b)2 C) (a – b)2 D) a2 – b

Answer»

A) (a + b) (a – b)

Correct option is (A) (a + b) (a – b)

\(96\times104\) = (100 - 4) \(\times\) (100 + 4)

Let a = 100, b = 4

Then \(96\times104\) = (a - b) (a + b)

\(\therefore\) Formula used in product of \(96\times104\) is (a + b) (a – b).
