Question

2. If p(x) = x^2 - 6x + 8, then find the value of p(2)+p(1)-p(1/2)
​

Answer 1

Answer:

-15/4

Step-by-step explanation:

Factorize p(x) as:

p(x) = (x-2)(x-4)

now substitute values,

0 + 3 - 27/4 = -15/4

Answer 2

Answer:

p(2)= 2²-6(2)+8

so p(2) is 4-12+8

p(2)=0

p(1)= 1-6+8= 3

P1/2= 1/4-3+8=.1/4+5=9/4

hence

3-9/4= 3/4
