1. For the following pairs of ordered bases $\beta$ and $\beta'$ for $P\_2(R)$ , find the change of coordinate matrix that changes $\beta'$ -coordinates into $\beta$ -coordinates.\
   $\beta;={1,x,x^2},;;\beta'={x^2+x+4,4x^2-3x+2,2x^2+3}$
2. prove that the determinant of the Vanderbilt matrix

$1 \quad a \quad a^2 $

$1 \quad b \quad b^2 $

$1 \quad c \quad c^2 $

is $(b-a)(c-a)(a-b)$. Can you generalise the result for $n\*n$ Vanderbilt Matrix?
