I am desperate because I try to solve the following equation with mei Casio Classpad.
1 x x2 x3 a 0
1 x+1 x2+2x x3+3x b 0
1 x+2 x2+4x+2 x3+6x+3 * c = 0
1 x+3 x2+6x+6 x3+9x+9 d x+1
It is a 4x4 matrix and I want to calculate the variables in dependence of x.
Would someone help me with the input.
I would be very grateful.
