Question

If p(x)=5x^2-4x+5 then evaluate for p(2)-p(-1)+p(1÷2)

Answer 1

Answer:

7.25

Step-by-step explanation:

p(x) =5x^2-4x+5

lf p(2)= 5(2)^2-4(2)+5

=20-8+5

=25-8

= 17

lf p(-1)= 5(-1)^2-4(-1)+5

=5+4+5

=14

if p(1/2)= 5(1/2)^2-4(1/2)+5

=5/4-4/2+5

=5-8+20/4

= -8+25/4

=17/4

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

= 17-14+17/4

= 7.25

hope it is correct
