प्रश्न

Check whether p(x) is a multiple of g(x) or not:

p(x) = x3 – 5x2 + 4x – 3, g(x) = x – 2

योग

उत्तर

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.
