Answer 1

Answer:

(7m + (5 • (n2))) • (7m - 5n2)

(7m + 5n2) • (7m - 5n2)

 3.1      Factoring:  7m-5n2 

Theory : A difference of two perfect squares,  A2 - B2  can be factored into (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

         A2 - AB + BA - B2 =

         A2 - AB + AB - B2 = 

         A2 - B2

Note :  AB = BA is the commutative property of multiplication. 

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Check :  7  is not a square !! 

Ruling : Binomial can not be factored as the

difference of two perfect squares

= (7m + 5n2) • (7m - 5n2)
