1.	If A = `(x - a) (x - b) (x -c) "……" ( x- z)` , then the number of terms in the expansion of (a + A) (b + A) ( c + A) …. (z + A) is `"________"`.A. 1B. 27C. 56D. 54
Answer» Correct Answer - A A = (x-a) (x- b) (x-c) ..... (x-x) ......(x-z) = 0 (a + A) (b + A) (c + A)..... (z + A) = (a + 0) (b + 0) (c +0) ------------ (z + 0) = a.b.c......z `therefore` There is only one term . Hence, the correct option is (a) .

Which of the following is/are perfect squares ?A. `16a^(2) + 36b^(2) - 48 ab`B. `9x^(2) + 18xy + 9y^(2)`C. Both (a) and (b)D. Neither (a) nor (b)
If `a + (1)/(a) = 6` , then find `a^(4) + (1)/(a^(4))`.
Find the product of (3a + 4b) and (3a - 4b) and verify it when a = -1 and b = 1 .
If `3x + (1)/(x) = 6` , then find `9x^(2) + (1)/(x^(2))`.A. 24B. 27C. 30D. 33
Divide `(a^(4) - b^(4))` by a - b and find the quotient and remainder .
Divide `18x^(4) - 27 x^(3) + 6x` by 3x.
