# Use a suitable identity to get each of the following products.(i) (ii) (iii) (iv) (v) (vi) (vii)(viii)(ix) (x)

(i) Using Identity (a + b)2 = a2 + 2ab + b2

In the given expression a = x, b = 3

On substituting these values in the above identity, we get

(ii) Using Identity (a + b)2 = a2 + 2ab + b2

In the given expression a = 2y, b = 5

On substituting these values in the above identity, we get

(iii) Using Identity (a - b) 2 = a2 - 2ab + b2

In the given expression a = 2a, b = 7

On substituting these values in the above identity, we get

(iv) Using Identity (a - b)2 = a2 - 2ab + b2

In the given expression a = 3a, b = 1/2

On substituting these values in the above identity, we get

(v) Using Identity (a + b)(a - b) = a2 - b2

In the given expression a = 1.1m, b = 0.4

On substituting these values in the above identity, we get

(vi) Using Identity (a + b)(a - b) = a2 - b2

In the given expression a = b2, b = a2

On substituting these values in the above identity, we get

(vii) Using Identity (a + b)(a - b) = a2 - b2

In the given expression a = 6x, b = 7

On substituting these values in the above identity, we get

(viii)Using Identity (a - b) 2 = a2 - 2ab + b2

On substituting these values in the above identity, we get

(ix) Using Identity (a + b) 2 = a2 + 2ab + b2

In the given expression a =

On substituting these values in the above identity, we get

(x) Using Identity (a - b) 2 = a2 - 2ab + b2

In the given expression a =

On substituting these values in the above identity, we get
