Answer 1

HeyMate♥️...

From the quadratic equation...

a=5

b=2

c=-1

Sum of the zeroes = -b/a

Alpha + bita = -b/a

alpha + bita = -2/5

i hope it helps you❤️...

Answer 2

Answer:

-2/5

Step-by-step explanation:

Since the equation is :

5x² + 2x - 1

And the general equation is :

ax² + bx + c

Therefore,

Alpha + Beta (sum of zeros) = -b/a

Thus,

Alpha + Beta = -2/5.
