If X = `2x^(2) , Y = 4x^(6) - 6x^(4)` , then find the value of `(Y)/(X)` when x = 1 .A. `-4`B. 2C. `-1`D. 3

Answer» Correct Answer - C
Given X = `2x^(2)`,
`X = 4x^(6) - 6x^(4) ` and x = `-1` .
`(Y)/(X) = (4x^(6) - 6x^(4))/(2x^(2))`
`= 2x^(4) - 3x^(2)`
`= 2 (-1)^(4) - 3(-1)^(2) = -1` .
Hence , the correct option is (c) .
