Question

sum of zeroes of polynomial x³-2x²+3x-4​

Answer 1

$Compare \: given \: polynomial \\x^{3}-2x^{2}+3x-4 \:with \:ax^{3}+bx^{2}+cx+d ,\:we\\get$

$a = 1 ,b = -2 ,\:c = 3 \:and \:d = -4$

$Sum \:of \:the \: zeroes = \frac{-b}{a} \\= \frac{-(-2)}{1} \\= 2$

Therefore.,

$\red{ Sum \:of \:the \: zeroes }\green{= 2}$
