Answer:
The sum and product of the zeroes of the polynomial are 2.5 and -4 respectively.
Step-by-step explanation:
The given polynomial
p(x)=2x^3-5x^2-14x+8p(x)=2x
3
−5x
2
−14x+8
If a three degree polynomial is f(x)=ax^3+bx^2+cx+df(x)=ax
3
+bx
2
+cx+d , then
Sum of zeroes = -b/a
Product of zeroes = -d/a
In the given polynomial a=2, b=-5, c=-14 and d=8.
Sum of zeroes = -(-5)/(2) = 2.5
Product of zeroes = -(8)/(2) = -4
Therefore, the sum and product of the zeroes of the polynomial are 2.5 and -4 respectively.
