$\Large\fbox{\color{purple}{ SOLUTION }}$

Given:-

$3 {x}^{2} + 5x + 7 = 0$

General form of quadratic eq.

$a {x}^{2} + bx + c = 0$

since,

sum of zeroes will be. =

$( - b )\div a$

therefore,

sum of zeroes will be = -5/3

Answer 2

Step-by-step explanation:

Given:-

3 {x}^{2} + 5x + 7 = 03x

2

+5x+7=0

General form of quadratic eq.

a {x}^{2} + bx + c = 0ax

2

+bx+c=0

since,

sum of zeroes will be. =

( - b )\a(−b)÷a

therefore,

sum of zeroes will be = -5/3
