Question

8.The sum and product of the zeros of quadratic polynomial 4x² -1 is *
a) -2, 0
b) 0, 4
c) 0,-1/4
d) 1/4, 0​

Answer 1

Given :- The sum and product of the zeros of quadratic polynomial 4x² -1 is *

a) -2, 0

b) 0, 4

c) 0,-1/4

d) 1/4, 0

Solution :-

we know that, for quadratic polynomial ax² + bx + c ,

• sum of zeros = (-b/a)
• product of zeros = c/a .

comparing given quadratic polynomial 4x² - 1 with ax² + bx + c we get,

• a = 4
• b = 0
• c = (-1)

so,

→ sum of zeros = (-b/a) = 0/4 = 0

→ product of zeros = c/a = (-1/4)

therefore, option (c) 0, (-1/4) is correct answer.
