" 16."quad (x^(2)-6x+9)/(5-4x-x^(2))>=0

(4x^(2)-11x+6)/(16x^(2)-9)

Prove that, lim_(xtooo)(4x^(3)-5x^(2)+6x+9)/(3x^(4)+4x^(2)-11)=0

The equation whose roots are 0 , 0, 2, 2, -2, -2 is A) x^(6)+8x^(4)-16x^(2)=0 B) x^(6)-4x^(4)-16x^(2)=0 C) x^(6)-8x^(4)+16x^(2)=0 D) x^(6)+4x^(4)+16x^(2)=0

(16x^(2)-20x+9)/(8x^(2)+12x+21)=(4x-5)/(2x+3)

Solve by the method of completing the square: (1) 9x^(2)-15x+6=0 (2) 5x^(2)-6x-2=0

Evaluate lim_(x to sqrt(3)) (3x^(8) + x^(7) - 11x^(6) - 2x^(5) 9x^(4) - x^(3) + 35x^(2) + 6x + 30)/(x^(5) - 2x^(4) + 4x^(2) - 9x + 6)

Evaluate lim_(x to sqrt(3)) (3x^(8) + x^(7) - 11x^(6) - 2x^(5) - 9x^(4) - x^(3) + 35x^(2) + 6x + 30)/(x^(5) - 2x^(4) + 4x^(2) - 9x + 6)

Simplify (81x^(4)-16x^(2)+32x-16)/(9x^(2)-4x+4)
