Question

how many maximum minimum of. of zeroescan a quadratic polynomial have​

Answer 1

Answer:

Hence a quadratic polynomial has maximum of 2 zeroes.

C

Answer 2

A quadratic polynomial has maximum two zeroes.

Let us take an example:

Factorise the quadratic polynomial x2

+2x−15=0 as shown below:

x2 +2x−15=0

x2 +5x−3x−15=0

x(x+5)−3(x+5)=0

x−3=0 or x+5=0

x=3 or x=−5

Therefore, the zeroes of the polynomial x

2

+2x−15 are 3,−5.

Hence a quadratic polynomial has maximum of 2 zeroes.
