Analyze the roots of the following equations: (i) 2x^(3) - 9x^(2) + 12x - (9//2) = 0 (ii) 2x^(3) - 9x^(2) + 12x - 3 = 0

Find the square root of 4x^(6) - 12x^(5) + 9x^(4) + 8x^(3) - 12x^(2) + 4

Prove that : 2x^(4) - 9x^(3) + 21x^(2) - 26x + 12 is completely divisible by 2x - 3.

If x^(4) + 4x^(3) - 2x^(2) - 12x + 9 = 0 has a pair of equal roots then the roots are
