Question

The sum of the zeroes of polynomial 3x square- 10x + 3

Answer 1

Answer:

The Correct answer is 3

Step-by-step explanation:

Given,

$Let \: p(x)=0 \: \\ </p><p>Therefore \: \: 3x {}^{2} - 10x + 3 = 0 \\ =3x {}^{2} - x - 9x + 3 = 0 \\ = x(3x - 1) - 3(3x - 1) = 0 \\ = (3x - 1)(x - 3) = 0 \\ Separate \: into \: two \: possible \: cases. \\ therefore \: 3x - 1 = 0 \\ = x = \frac{1}{3} \\ And \\ x - 3 = 0 \\ = x = 3 \\ Therefore \: the \: sum \: of \: the \: zeroes \: of \: the \: given \: polynomial \: is \\ \frac{1}{3} + 3 \\ = 3$
