Question

The sum of zeroes of cubic polynomial 2x3 - 5x2 - 14x + 8 will be :​

Answer 1

Answer:

5/2

Step-by-step explanation:

Standard form of cubic polynomial :

ax³+bx²+cx+d = 0

where -b/a = sum of the zeroes

c/a = sum of products of 2 zeroes

-d/a = product of all the zeroes

Therefore sum of the zeroes = -(-5)/2 = 5/2

Answer 2

Answer

4-14x

Step-by-step explanation:

6-10-14x+8

-4+8-14x

=4-14x
