3) 72[tex]x^{5}[/tex]-43[tex]x^{4}[/tex]+98x³-69x²+43x-20

4) 42[tex]x^{6}[/tex]+35[tex]x^{5}[/tex]-18x²-15x

5) 24[tex]x^{6}[/tex]-50[tex]x^{5}[/tex]+55[tex]x^{4}[/tex]-26x³+47x²-39x-21

Explicación paso a paso:

1)

(2x-4)(8x+3) = 16x²+6x-32x-12 = 16x²-26x-12

2)

(4x²+5x-6)(7x²+2x) = 28[tex]x^{4}[/tex]+35x³-42x²+14x³+10x²-12x = 28[tex]x^{4}[/tex]+49x³-32x²-12x

3)

(9x³-2x²+7x-5)(8x²-3x+4) = 72[tex]x^{5}[/tex]-16[tex]x^{4}[/tex]+56x³-40x²-27[tex]x^{4}[/tex]+6x³-21x²+15x+36x³-8x²+28x-20 = 72[tex]x^{5}[/tex]-43[tex]x^{4}[/tex]+98x³-69x²+43x-20

4)

(7[tex]x^{5}[/tex]-3x)(6x+5) = 42[tex]x^{6}[/tex]+35[tex]x^{5}[/tex]-18x²-15x

5)

(3[tex]x^{4}[/tex]-4x³+5x²-x+7)(8x²-6x-3) = 24[tex]x^{6}[/tex]-32[tex]x^{5}[/tex]+40[tex]x^{4}[/tex]-8x³+56x²-18[tex]x^{5}[/tex]+24[tex]x^{4}[/tex]-30x³+6x²-42x-9[tex]x^{4}[/tex]+12x³-15x²+3x-21 = 24[tex]x^{6}[/tex]-50[tex]x^{5}[/tex]+55[tex]x^{4}[/tex]-26x³+47x²-39x-21
