Question

() Sum of the roots of the quadratic equation 5x2 + 5x + 2 = 0 is
(A)-2
(B) 2.
(C) -1
(D) 1​

Answer 1

Answer:

→ -1

given quadratic equation is

5x² +5x +2 = 0

where, a = 5, b= 5, c = 2

so, sum of roots = -b/a = -5/5 = -1

Answer 2

Answer:

sum of roots = (-coefficient of x) / (coefficient of x²)

-b/a

-5/5

-1
