Question

find all the zeroes of the following polynomial ,when two of thier zeroes are given : p(x) = 2x^4+x^3-14x^2-19x-6, two zeroes are -2and-1

Answer 1

HOPE IT HELPS U.....

Answer 2

p(x) = 2x⁴ + x³ - 14x² - 19x - 6

Factorise:

p(x) = (2x + 1) (x + 1) (x + 2) (x - 3)

Find the zeros:

2x + 1 = 0

x = -1/2

x + 1 = 0

x = 01

x + 2 = 0

x = -2

x - 3 = 0

x = 3

Answer: The other two zeros are -1/2 and 3
