2x^(2)+3x+1-:x+2

Simplify each of the following 2x^(2) + 3x (1 -2x^(3)) + x(x + 1)

Without expanding a determinant at any stage, show that |{:(x^(2)+x, x+1, x+2),(2x^(2) +3x-1, 3x, 3x-3),(x^(2) +2x+3, 2x-1, 2x-1):}|=xA+B where A and B are determinants of order 3 not involving x.

Solve : (2x^2 - 3x+1) (2x^2 + 5x + 1) = 9x^2 .

Find the no of solution (2x^(2)-3x+1)(2x^(2)+5x+1)=4x^(2)

Divide 2x^(2)+3x+1 by x+2 .

Divide 2x^(2)+3x+1" by "x+2 .

Divide 2x^2 + 3x+ 1 by x+ 2 .
