1.

The remainder when x3 + 2x2 + 3x + 4 is divided by (x – 1) is A) 10 B) 6 C) 4D) 2

Answer»

Correct option is (A) 10

Let p(x) = \(x^3+2x^2+3x+4\)

When p(x) is divided by \((x-1)\) then remainder will be p(1).

\(\therefore\) Remainder = p(1) \(=1^3+2\times1^2+3\times1+4\)

= 1+2+3+4 = 10

Correct option is A) 10
