1.	`(4x^(2) + 19x^(2) + 25) div (2x^(2) - x + 5) = "_________"` .A. `2x^(2) - 9x + 5`B. `2x^(2) + 9 x + 5`C. `2x^(2) + x + 5`D. `2x^(2) - x + 5`
Answer» Correct Answer - C `4x^(4) + 19 x^(2) + 25 ` = `(2x^(2))^(2) + (5)^(2) + 20x^(2) - x^(2)` `= (2x^(2) + 5)^(2) - x^(2)` = `(2x^(2) + x + 5) (2x^(2) - x + 5)` `implies (4x^(4) + 19x^(2) + 25)/(2x^(2) - x+ 5) = 2x^(2) + x+ 5`. Hence , the correct option is (c).

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.
`x^(3) + xy^(2) - x^(2) y - y^(3) = "_______"`A. `(x^(2) + y^(2)) (x + y)`B. `(x^(2) + y^(2))( x- y)`C. `(x-y) (x + y)^(2)`D. `(x + y) (x- y)^(2)`
An equation which is true for all real values of its variables is called an identify .
