Question

the sum of the zeroes of the polynomial 3x square- 10x +3 is.​

Answer 1

Answer:

$other \: way \: of \: doing \: is \\ \\ 3x ^{2} - 10x + 3 \\ \\ = 3x ^{2} - (9 + 1)x + 3 \\ \\ = 3x ^{2} - 9x - x + 3 \\ \\ = 3x(x - 3) - 1(x - 3) \\ \\ = (3x - 1)(x - 3) \\ \\ either \: 3x - 1 = 0 \\ \\ = > 3x = 1 \\ \\ = > x = \frac{1}{3} \\ \\ or \: x - 3 = 0 \\ \\ = > x = 3 \\ \\ so \: adding \: the \: two \: roots \\ \\ \frac{1}{3} + 3 \\ \\ = \frac{1 + 9}{3} \\ \\ = \frac{10}{3}$

⭐ In either way we get 10 / 3 .
