Answer 1

4(x+9) 10(×-2) 4-3x x-7 5x-10 4x 2×+1=$-3x^2-603x-2879$

$4\left(x+9\right)\times \:10\left(\left(-2\right)\right)\times \:4-3xx-75x-104x\times \:2+1=-3x^2-603x-2879\\\\\\4\left(x+9\right)\times \:10\left(\left(-2\right)\right)\times \:4-3xx-75x-104x\times \:2+1$

$-4\times \:10\times \:2\times \:4\left(x+9\right)-3xx-75x-104\times \:2x+1\\\\4\left(x+9\right)\times \:10\times \:2\times \:4=320\left(x+9\right)\\\\3xx=3x^2\\\\104x\times \:2=208x\\\\-320\left(x+9\right)-3x^2-75x-208x+1\\\\-320\left(x+9\right):\quad -320x-2880\\\\-320x-2880-3x^2-75x-208x+1\\\\\mathrm{Simplificar}\:-320x-2880-3x^2-75x-208x+1:\quad -3x^2-603x-2879\\\\\\-3x^2-603x-2879$
