Question

without finding the zeroes of qubic polynomial x3-8x2+17x-10, write the sum of zeroes, the product of zeroes and the sum of multiplication of two zeroes .​

Answer 1

$\sf \rm{ \large{sum \: of \: zero \: of \: cubic \: polynomial \: }}$

$\sf \rm{ = \frac{ - b}{a} = \frac{( - 8)}{1} = 8}$

$\sf \red{mor}{ \pink{ning}} \: { \pink{mor}{ \purple{ning}}}$
