    \huge\mathcal\color{purple}Answer

    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 x2+2x−15 are 3,−5.

    Hence a  quadratic polynomial has maximum of 2

    Answer:

    ans is b)2

    Step-by-step explanation:

    Because quadratic polynomial have degree of 2 so the no. of zeroes is equal to the degree of the polynomial. It is a trick so that you can give answer instantly. Make me brainliest
