If find the values of
(i) (ii)

(i)

We know that,

From formula (a + b)² = a² + b² + 2ab

So, by putting the values , we get,

= 4² =

(ii)

We know that,

From formula (a + b)² = a² + b² + 2ab

So, by putting the values , we get,

= 14² =

Find the value of the expression (64x² + 81y² + 144xy), when x = 11 and .

Find the value of the expression (36x² + 25y² – 60xy) when and

If find the value of

(i) (ii)

Find the continued product:

(i) (x +1)(x – 1)(x² + 1)

(ii) (x- 3)(x + 3)(x² + 9)

(iii) (3x – 2y)(3x + 2y)(9x² + 4y²)

(iv) (2p + 3)(2p – 3)(4p² + 9)

If find the values of(i) (ii)
