Use suitable identities to find the following product: (3 – 2x) (3 + 2x)
Using identity, (x + y) (x – y) = x2 – y2 (3 - 2x)(3 + 2x) = (3)2 – (2x)2 = 9 - 4x2
Use suitable identities to find the following product: (y2 + 32)(y2 – 32)
Use suitable identities to find the following product: (3x + 4) (3x – 5)
