Question

.Find the zeroes of the polynomial f(x) = 2x³ – 11x² +
10x + 8, if the product of its two zeroes is 8​

Answer 1

Step-by-step explanation:

let a,b,c be the roots so ab=8

and abc=-8/2

c=-1/2

dividing the equation with 2x+1 we get x²-6x+8

putting x²-6x+8=0

we get x=4,2

so the roots are 4,2,-1/2
