Question

pls answer and explain​

Answer 1

Hey Mate

Your answer is here

Let P( X ) = x^3 + ax^2 + bx + c

Assume r , s and t are roots of given polynomial.

Then ,,

-a = r + s + t

b = rs + ts + rt

&

-c = est

Given that ,,,

r + s + t = 3

rs + st + rt = -10 &

rst = -24

So,,

-a = 3

a = -3

and

b = -10 &

-c = -24

c = 24

After putting all these values in polynomial equation we get ,,,,

P ( X ) = x^3 - 3x^2 - 10x + 24

So,,, Option "C" is the correct answer.

Thanks,,,
