Using remainder theorem, find the remainder on dividing f(x) by (x + 3) where f(x) = 2x2 – 5x + 1 - Mathematics

Using remainder theorem, find the remainder on dividing f(x) by (x + 3) where f(x) = 2x² – 5x + 1

बेरीज

Let x + 3 = 0
⇒ x = -3
Substituting the value of x in f(x),
f(x) = 2x² – 5x + 1
∴ f(-3) = 2(-3)² - 5(-3) + 1
= 18 + 15 + 1
= 34.
Hence Reminder = 34.
