SOLUTION

TO CHOOSE THE CORRECT OPTION

If a polynomial 2x² - 7x - 1 is divided by (x + 3), then the remainder is

(a) - 4

(b) 38

(c) - 3

(d) 2

EVALUATION

Let f(x) = 2x² - 7x - 1

g(x) = x + 3

For Zero of the polynomial g(x) we have

g(x) = 0

⇒ x + 3 = 0

⇒ x = - 3

By Remainder Theorem the required Remainder when f(x) is divided by g(x) is

= f( - 3)

= 2 × ( - 3)² - 7 × ( - 3 ) - 1

= 18 + 21 - 1

= 38

FINAL ANSWER

Hence the correct option is (b) 38
