Question

(2x³-x2+x-4).(x³-x²+2x+5)=​

Answer 1

Respuesta:

2x3−x2+x−4)(x)(x3−x2+2x+5)

=((2x3−x2+x−4)(x))(x3+−x2+2x+5)

=((2x3−x2+x−4)(x))(x3)+((2x3−x2+x−4)(x))(−x2)+((2x3−x2+x−4)(x))(2x)+((2x3−x2+x−4)(x))(5)

=2x7−x6+x5−4x4−2x6+x5−x4+4x3+4x5−2x4+2x3−8x2+10x4−5x3+5x2−20x

=2x7−3x6+6x5+3x4+x3−3x2−20x
