Question

check weather -1is zero of polynomial x^_1​

Answer 1

Answer:

ANSWER

Let p(x)=x2−3x+2

Replace x by 2

p(2)=(2)2−3(2)+2

=4−6+2=0

Also replace x by 1

p(1)=(1)2−3(1)+2

=1−3+2

=0

Hence, both 2 and 1 are zeroes of the polynomial x2−3x+2.

It is a quadratic polynomial. Hence, a quadratic polynomial has two zeroes.
