Question

11. If – 1 is a zero of the polynomial f(x)= x^2-7x-8 then other zero is (a) 4 (b) 8 (c) 1 (d) -4​

Answer 1

Answer:

another zero of the polynomial is 8.

Step-by-step explanation:

64-56-8=0

Answer 2

Answer:

Step-by-step explanation:

The solution of the question is here -

Let the zeroes be a and b

Then, a = - 1 , a + b = - (- 7) / 1

Hence, b = 7+ 1 = 8

So, the other zero is 8.

Therefore, option (b) 8 is the correct answer.
