" 6."x^(4)+10x^(3)+35x^(2)+50x+24

If x= -5 + sqrt(-16) , find the value of x^(4) + 9x^(3) + 35x^(2)-x + 4

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)

Which of the following is to be added to make x^(6) -6x^(4) + 4x^(3) + 8x^(2) - 10x + 3 a perfect square ?

Factorise each of the following polynomials using synthetic division: (i) x^(3) -3x^(2) -10x +24 (ii) 2x^(3) -3x^(2) -3x +2 (iii) -7x +3+4x^(3) (iv) x^(3) +x^(2) -14x -24 (v) x^(2) - 7x+ 6 ( vi ) x^(3) -10x ^(2) -x+ 10

The equation whose roots are exceed by 2 then those x^(4) + x^(3) - 10x^(2) + 4x + 24 = 0 is

to remove the 2^(nd) term of the equation x^4 -10 x^3 +35 x^2 -50 x^2 - 50 x+ 24=0 , diminish the roots by

The roots of the equation x^(4)-10x^(3)+50x^(2)-130x+169=0 are of the form a+-ib and b+-ia, the (a,b)=
