1. Problem Description

We are given the polynomial P(x)=4x34x+1P(x) = 4x^3 - 4x + 1. We want to find the remainder when P(x)P(x) is divided by 2x32x - 3.

2. Solution Steps

By the Remainder Theorem, if we divide a polynomial P(x)P(x) by axbax - b, the remainder is P(ba)P(\frac{b}{a}).
In this case, we are dividing by 2x32x - 3, so a=2a = 2 and b=3b = 3. Therefore, we need to find P(32)P(\frac{3}{2}).
We have:
P(x)=4x34x+1P(x) = 4x^3 - 4x + 1
P(32)=4(32)34(32)+1P(\frac{3}{2}) = 4(\frac{3}{2})^3 - 4(\frac{3}{2}) + 1
P(32)=4(278)4(32)+1P(\frac{3}{2}) = 4(\frac{27}{8}) - 4(\frac{3}{2}) + 1
P(32)=2726+1P(\frac{3}{2}) = \frac{27}{2} - 6 + 1
P(32)=2725P(\frac{3}{2}) = \frac{27}{2} - 5
P(32)=272102P(\frac{3}{2}) = \frac{27}{2} - \frac{10}{2}
P(32)=172P(\frac{3}{2}) = \frac{17}{2}

3. Final Answer

P(32)=172P(\frac{3}{2}) = \frac{17}{2}
