Question

prasee that both zero of the quader
palynamial e + 9 9 7+ You are nega​

Answer 1

Answer:

The zeroes of the quadratic polynomial x2 + 99x + 127 are

(a) Both positive

(b) Both negative

(c) One positive and one negative

(d) Both equal

Step-by-step explanation:

(b) Let given quadratic polynomial be p(x) =x2 + 99x + 127.

On comparing p(x) with ax2 + bx + c, we get

a = 1, b = 99 and c = 127

Hence, both zeroes of the given quadratic polynomial p(x) are negative.

Alternate Method

the above condition.

So, both zeroes of the given quadratic polynomial are negative.
