Question

verify whether following are zeros of polynomial.
p(x)=x²-1,x=1,x=-1​

Answer 1

in the equation they given p(x)=x²‐1 find the zeroes of polynomial

in the question they x=–1 or x=1

now,we will substitute x=–1 and we will see

p(x)=–1²–(–1)=0

and now we check if x=1

p(x)=1²–1=0

which means

both are zeroes of polynomial
