Question

решите у=(4х3-2х2-5х)*(х2-7х) :у=(9-2х)*(2х3-9х2+1)

Answer 1

1) y = 4x^5 - 28x^4 - 2x^4 + 14x^3 - 5x^3 + 35 x^2 = 4x^5 - 30x^4 + 9x^3 + 35x^2

2) 18x^3 - 81x^2 + 9 - 4x^4 + 18x^3 - 2x = -4x^4 + 36x^3 - 81x^2 - 2x + 9

Answer 2

у=4Х⁵-28Х⁴-2Х⁴+14Х³-5Х³+35Х²=4Х⁵-30Х⁴+9Х³+35Х²

 

 

у=18Х³--81Х²+9-4Х⁴+18Х³-2Х=-4Х⁴+36Х³-81Х²-2Х+9
