Question

The zeroes of the quadratic polynomial x 2 + 99x + 127 are:………. A)Both positive B) Both negative C) one positive one negative D)Both equal

Answer 1

Hi ,

We know that,

In a quadratic expression ax²+ bx + c

If a , b , c will have the same sign

then the both zeroes of the

expression are negative

Compare given expression

x² + 99x + 127 with ax² + bx + c ,

a = 1 , b = 99 ,c = 127

All are positive sign ,

Therefore ,

The expressions both zeroes has

negative sign.

Option B ) is correct.

I hope this helps you.

:)

Answer 2

Answer:

B) both negative

Step-by-step explanation:

When a>0,b>0,c>0

a<0,b<0,c<0

Means a,b,c have same sign in a quadratic equations

So its both zeros have negative sign

Here a=1

b=99

c=127

All have same sign and are positive
