(Cbse 2014, 2015)

Please answer correctly... ​

Answer 1

a) 1 polynomial x-1 b) -2 polynomial x square +3x

Answer 2

ANSWER :

ii) zeroes : -2,0 Polynomial: x^2 + 2x

iii)zeroes : 1       Polynomial: x-1

Step-by-step explanation:

Answer:

if a graph of polynomial P(x) is shown, number of zeroes of given polynomial equals number of intersections done by graph on X - axis.

for instance, if a graph of polynomial P(x) cuts the x - axis at two different points , it means P(x) has two zeroes.

now see graphs,

figure -(i) [left side mentioned as fig (i) ] : here we see graph of polynomial cuts x - axis at two different points i.e., 0 and -2. hence, polynomial has two zeroes. and these are ; 0 and -2.

figure -(ii) : here we see graph of polynomial cuts x - axis at only one point i.e., 1 therefore, polynomial has only one zero. and that is ; 1.
