Question

The factorization of 9 2 + 9 + 2 ?​

Answer 1

Rewrite 9x2 9 x 2 as (3x)2 ( 3 x ) 2 . Rewrite 25 as 52 . Since both terms are perfect squares, factor using the difference of squares formula, a2−b2=(a+b)(a−b) a 2 - b 2 = ( a + b ) ( a - b ) where a=3x a = 3 x and b=5 .

Answer 2

Answer:

Positive factors of 92 are: 92,9,2

Sum of all the factors is 92 + 9 + 2 = 103

Therefore, sum of all the positive factors of 92 is 103.

this much only I know
