Question

7. Verify that
(i) 1 and 2 are the zeros of the polynomial, p(x) = x² - 3x +2​

Answer 1

Answer:

p(1)=1²-3(1)+2

p(1)=1-3+2

p(1)=3-3

p(1)=0

p(1) is the zero the polynomial

p(2)=2²-3(2)+2

p(2)=4-6+2

p(2)=-2+2

p(2)=0

p(2) is also the zero the polynomial.

Answer 2

Answer:

Lets solve the polynomial :

=> x²-3x²+2=0

=> x²-x(2+1)+2=0

=> x²-2x-x+2=0

=>x(x-2)-1(x-2)=0

=>(x-2)(x-1)=0

=>x=2 or x=1
