Question

find the zeros of the polynomial x cube minus 6X square + 3 X + 10 it is given that the zeros are in AP​

Answer 1

Answer:

x³-6x²+3x+10

Let a, b, c are zeroes of equation

They are in a. P

2b=a+c

From equation a+b+c=6

3b=6, b=2

ab+bc+ca=3

2a+2c+ca=3. abc=-10,ac=-5

2a+2c-5=3

a+c=4

a=2,b=2, c=2 the roots are equal.
