Question

sign of both the series at polynomial x2+99x+127 is ____ (A) positive (B)negative (C)same (D)opposite​

Answer 1

(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.

Answer 2

Answer:

B is the answer negative
