Use suitable identities to find the following products:
(i) (x + 4)(x + 10)
(x + 8)(x - 10)
(3x + 4)(3x - 5)
(3x + 4)(3x - 5)(3x + 4)(3x - 5) = (3x + 4) {3x + (- 5)}= (3x)2 + (4 + (- 5)} (3x) + (4)(- 5)| Using Identity IV= 9x2 - 3x - 20.
Use suitable identities to find the following products:(3 - 2x)(3 + 2x)
