Answer 1

Step-by-step explanation:

$\sf{\underline{\underline{\large{\bold{Answer:-}}}}}$

p(x)=x²-4x+3

p(2)=(2)²-4(2)+3=4-8+3=4-5=-1

p(-1)=(-1)²-4(-1)+3=1+4+3=8

p(1/2)=(1/2)²-4(1/2)+3

=1/4-2+3

=1-8+12/4=1+4/4=5/4

p(2)-p(-1)+p(1/2)

=-1-(8)+5/4

=-9+5/4

=-36+5/4=-31/4 is the answer

Hence proved

Answer 2

HERE IS UR ANSWER DEAR,

p(x) = x² -4x + 3

p(2) = (2)²-4(2)+3

= 4-8+3

=-4+3

=-1

p(-1)= (-1)²-4(-1)+3

= 1 +4 +3

= 8

p(1/2) = (1/2)²-4(1/2) +3

= 1/4 - 2 +3

= 1/4+1

= 1+4/5

= 5/4

= p(2)-p(-1)+p(1/2)

= -1 -8+5/4

=( -4 -32+5)/4

= -31/4
