" (iii) "(x^(2)+3x-9)/(x^(2)-9x+3)

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

x^(3)-3x^(2)-9x+20 is

Factorise: (i) x^(3)-2x^(2)-x+2 (ii) x^(3)-3x^(2)-9x-5 (iii) x^(3)+13x^(2)+32x+20 (iv)

If x is real,the maximum value of (3x^(2)+9x+17)/(3x^(2)+9x+7) is
