Show that `(x+ 2)` is a factor of `x^(3) -4x^(2) - 2x + 20`

Show that x + 4 is a factor of x^(3) + 6x^(2) - 7x - 60

Show that (x-5) is a factor of x^(3)-3x^(2)-4x-30 .

Show that, x -2 is a factor of x ^(3) - 2x ^(2) + 3x - 6.

Using the factor theorem, show that (x-2) is a factor of x^(3) +x^(2) -4x -4 . Hence factorise the polynomial completely.

Show that (2x-3) is a factor of (x+2x^(3)-9x^(2)+12) .

Show that (x+2) is a factor of f(x) = x^(3) + 5=4x^(2) + x - 6.

By actual division show that x+2 is a factor of x^(3)+4x^(2)+3x-2 .

Show that (x+2) is a factor x^4-x^2-12

By actual division show that x+2 is a factor of x^(3)+4x^(2)+3x^(2)-20 .

Show that: 2x-3 is a factor of x+2x^3-9x^2+12
