= (x + y) {(x)2 - xy + (y))
[Using identity, (x + y) (x2 - xy +
= (x3)3 + (13)3
[Again using identity (x + y) (x2 - xy +
= x + y
Exercise 9.4
Find the following products by using appropriate identities:
1. (x + 5) (x2 - 5x + 25)
2. (2x + 3) (4x2 - 6x +9)
3. x(4x + 5y) (16x2 - 20xy + 25y2)
4. (3x + 4y) (9x2 - 12xy + 16y2)
5. (4xy - 1)(16x?y2 + 4xy + 1)
6. (x2 + y2) (x4 – x2y2 + y4)
7. (2x2 - 1)(4x4 + 2x2 + 1)
8. (x - 1)(x2 + x + 1)(x6 + x3 + 1)
