" 4."x^(2)+19x-150

…………is one of the factors of 2x^(4) + x^(3) - 14 x^(2) - 19x - 6 .

The roots of x^(4) - 5x^(3) + 3x^(2) + 19x - 30 = 0 are

If 8x^(3) - 14x^(2) - 19x - 8 is divided by 4x+ 3 then find the quotient and the remainder.

x^(2)-19x+84

Find the quotient and remainder for the following using synthetic division : ( 8 x^(3) - 14x^(2) - 19x - 8) div ( 4x + 3)

(a) 6x^(2) + 19x + 15

x^(3)-19x-30

Factorise: z ^(2) +19z-150
