Question

sum of the zeros of 3x^2 =1 is​

Answer 1

Answer:

Step-by-step explanation:

In a general quadratic equation of form ax2+bx+c=0, sum of roots are by−b/a​.

In the given quadratic equation, 3x2−kx+6=0

a=3,b=−k,c=6

Sum of roots =−b/a​=−(−k)/3​=k/3​

and sum of roots is given 3

⇒k/3​=3

⇒k=9​

Answer 2

Answer:

$x {}^{2} = \frac{1}{3}$

$3 {x}^{2} = 1$

$x {}^{2} = \frac{1}{3}$

$x = \sqrt{ \frac{1}{3} }$

$x = + \frac{1}{3} \: \: \: and \: \: \: - \frac{1}{3}$

$sum = - \frac{1}{3} + \frac{1}{3}$

$sum = 0$
