If the each of algebraic expressions `lx^(2) + mx + n, mx^(2) + nx + l

1.	If the each of algebraic expressions `lx^(2) + mx + n, mx^(2) + nx + l and nx^(2) + lx + m` are prefect squares, then `(l +m)/(n) =` _____A. `-4`B. 6C. `-8`D. None of these
Answer» Correct Answer - A

If `sqrt((125 a^(6) b^(4) c^(2))/(5a^(4) b^(2))) = x, " then find " (x^(2))/(abc)`
Factorize `(1)/(6) a^(2) - a + (4)/(3)`
Factorize `m^(7) + m^(4)`
The LCM of the polynomials `(x^(2) + x - 2) (x^(2) + x -a) and (x^(2) + x -b) (x^(2) + 5x + a) " is " (x -1) (x +2) (x +3)`, then find the values of a and b
Find the value of `sqrt((a+b +c)^(2) + (a +b+c)^(2) + 2(c^(2) -a^(2) -b^(2) -2ab))`
Find the square root of `(x^(2) + 6x + 8) (x^(2) + 5x + 6) (x^(2) + 7x + 12)`
If `A = 3x^(2) + 5x -3 and B = 5x^(2) -7`, then `2A -B` is _____
Factorize `6x^(4) - 5x^(3) - 38x^(2) -5x +6`
Find the remainder if `x^(5) - 3x^(3) + 5x + 1` is divided by `2x -1`
Find the remainder when `x^(15)` is divided by `x -2`
