Question

Sum of the zeros of polynomial xcube–2xsquare+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.,

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