Question

Find the value of k, if 2x +1 is a factor of polynomial 2x³ - 11x² - kx + 1.​

Answer 1

Answer:

k is 7

as 2x - 1 is a factor of the given polynomial

this means on dividing them , the remainder will he 0.

so we using factor theorem we find x=-1/2

n then we put it in the given polynomial to get remainder in terms of k then equate it with 0
