Question

find the value of the polynomial P(x)= x³-3x²-2x+6 at x =√2

Answer 1

Given,

The given polynomial P(x) is x³-3x²-2x+6

To find,

The value of the polynomial P(x) at x =√2.

Solution,

We can simply solve this mathematical problem using the following process:

Mathematically, the value of a polynomial at a given value of the variable can be calculated by putting that value of the variable in the polynomial and solving it.

So, the value of the polynomial P(x) at x =√2 is:

P(√2) = (√2)³-3(√2)²-2(√2)+6

= 2√2 - 6 - 2√2 + 6

= 0

Hence, the value of the polynomial P(x) at x =√2 is 0.
