Question

a) (2x + 1)(x2 - x - 1) b) (3x – 2) - (2x2 + 4x – 3) c) (x2 + 2x – 3) · (3x2 + 5x -4​

Answer 1

Respuesta:

Corona.

Explicación paso a paso:

Calcular

$(3x - 2) (-x + x_{2} -1) (2x + 1) - c (4x + 2x_{2} - 3)$

Expandir

$2 + 3c - 2x_{2} - 2cx_{2} + 6x_{2} x^{2} + 3x - 4cx - xx_{2} -5x^{2} - 6x^{3}$
