Question

sum of the zeros of a quadratic polynomial 5 - 4 x + 12 x square​

Answer 1

$Compare \: given \: Quadratic\: expression \\12x^{2} - 4x + 5 \:with\:ax^{2} + bx + c, \:we \:get$

$a = 12, \: b = -4 , \: c = 5$

$Sum \:of \:the \: zeroes = \frac{-b}{a} \\= \frac{ -(-4)}{12} \\= \frac{4}{12} \\= \frac{1}{3}$

Therefore.,

$\red { Sum \:of \:the \: zeroes} \green {= \frac{1}{3} }$
