Question

check whether 2 and -3 are the zeroes of the polynomials p(x)=xsquare+2x-3
​

Answer 1

Answer:

2 is not a zero of given polynomial but - 3 is the zero of a given polynomial.

Step-by-step explanation:

Let's check it , starting with 2

p(2)=2^2+2×2-3=5 which is not equal to zero.

p(3)=(-3)^2-6-3=9-9=0.

Answer 2

here is your answer. put the value instead of x and check whether the result is zero. if zero then the number is the zero oof the polynomial.
