Question : 125 of 200

Marks: +1, -0

The remainder obtained when

7x^{2}-13x+5

is divided by

x-3

is

107
-29
29
-107

Solution:

Let

f(x)=7x^2-13x+5

From Remainder Theorem we know that the remainder obtained when f(x) is divided by (x – a) is equal to f(a).
∴ Required remainder

=f(3)=7(3)^2-13(3)+5

=63-39+5=29
