Question

Sum of the roots of the quadratic polynomial
$7 {x}^{2} - 3x + 1$
​

Answer 1

Answer:

3/7 is the right ans sum of roots is -b/a

Answer 2

$\boxed{\sf \: Sum \: of \: Roots \: = \frac{ - b}{a} }$

$7x {}^{2} - 3x + 1$

Here ⭐: -

a = 7

b = - 3

C = 1

According to given formula :-

$\sf \: Sum \: of \: Roots = \frac{ - b}{a} \\ \\ \implies \frac{ - ( - 3)}{7} \\ \\ : \implies \boxed{\green{ \sf \: \: \frac{3}{7} }}$
