Question

The sum of the zeroes of the
polynomial 5x2-bx - 8 is 2. Find the
value of b.​

Answer 1

Answer:

b = 10

Step-by-step explanation:

given,

sum = 2.

p(x)= 5x^2 - bx - 8

so,

sum = -(coefficient of x) / (coefficient of x^2)

2 = -(-b) / (5)

2. = b /5

2 × 5 = b

10 = b.

hope this helps you ♥️♥️

Answer 2

5 X 2 -b X - 8= 2

10-8 X - b = 2

2×-b = 2

b = 2/2

b=0
