2. Given that the polynomial 4x^3 +12x^2 -7x - 30 has a factor x+2 show that k=-7

1. first use polynomial division to divide 2x^3 - 3x^2 - 11x + 6 by (2x-1), once you're done, if there is no remainder, you have the quietnet is P, that is (2x^3 - 3x^2 - 11x + 6)/(2x-1) = P, multiplying both sides by (2x - 1) you obtain

2x^3 - 3x^2 - 11x + 6 = P(2x-1), your job will then be to factor the polynomial P you got from the division. This will be a quadratic polynomial so it should be easy to factor.

for 2. again divide  4x^3 +12x^2 -7x - 30 by (x+2), if there is no remainder, then it is a factor. It says show that k = -2 though. You'll have to provide more info there because you haven't told us what k represents.

A logarithm is just a misspelled algorithm.
