Question

Prove that the zeros of a quadratic polynomial x^2+99x+127

Answer 1

Hey

Your question:
Prove that the zeros of a quadratic polynomial x^2+99x+127 are negative.

Here is your answer,

here,
α+β=-b/a=-99
and
αβ=c/a=127
so,
the sum of zeroes is negative and product of zeroes is positive.. therefore, the zeroes are both negative.

Hope it helps you!
