Question

CBSE class 10 Maths Standard​

Answer 1

Answer:

all of them are polynomials

see it's very easy to understand whether given equation is a polynomial..

for example=2x+3

if u can draw separate graph for each term then it's a polynomial

here u can draw graph for y=2x

and y=3 which will be parallel to x axis

so there are two terms for which graph can be drawn individually...so combined y=2x+3 is a polynomial....

and there are only two quadratic equations becoz only two polynomial fulfill the format of ax^2+bx+c=0
