Question
Check whether p(x) is a multiple of g(x) or not:
p(x) = x3 – 5x2 + 4x – 3, g(x) = x – 2
Solution
According to the question,
g(x) = x – 2,
Then, zero of g(x),
g(x) = 0
x – 2 = 0
x = 2
Therefore, zero of g(x) = 2
So, substituting the value of x in p(x), we get,
p(2) = (2)3 – 5(2)2 + 4(2) – 3
= 8 – 20 + 8 – 3
= –7 ≠ 0
Hence, p(x) is not the multiple of g(x), the remainder ≠ 0.
