Question

Obtain all other zeroes of the polynomial f(x)=2x4+x3-14x2-19x-6 if two of its zeroes are -2 and -1​

Answer 1

Answer:

- 1/2 , 3 , -2 , -1

Step-by-step explanation:

f(x)=2 x∧4+x³-14x²-19x-6 = 0

2 x∧4+x³-14x²-19x-6 ÷ x² +3x + 2 = 2x² - 5x - 3

2x² - 5x - 3 = (2x + 1  )  ( x - 3  )

all Zeros = - 1/2 , 3 , -2 , -1
