Question
Find p(0), p(1), p(–2) for the following polynomial:
p(x) = 10x – 4x2 – 3
Advertisements
Solution
Consider the polynomial:
p(x) = 10x – 4x2 – 3
The value of given polynomial at x = 0 is
p(0) = 10 × 0 – 4 × 02 – 3
= –3
When x = 1
p(1) = 10 × 1 – 4 × 12 – 3
= 10 – 4 – 3
= 3
When x = –2
p(–2) = 10 × (–2) – 4 × (–2)2 – 3
= –20 – 16 – 3
= –39
