Question

Надо преобразуйте в многочлен выражения: 1) -(с+5)²-(с-4)*(с+3) 2) -(x+7)²-(x-2) 3) (c-1)(c++1)(c+2) 4) -2(x-1)x-(x+7)(x²-7x+49) 5) -(x+2)²-(x-3)(x+4) 6) (d+4)³-(d+1)(d+3)

Answer 1

1)-2с^2-9с-13 2)-x^2-15x-47

Answer 2

1) -(c+5)2-(c-4)*(c+3)=-(c2+10c+25)-(c2+3c-4c-12)=-c2-10c-25-c2+1c+12=-2c2-9c-13

2) -(x+7)2-(x-2)=-(x2+14x+49)-x+2=-x2-13x-47

3) (c-1)(c+1)-(c+1)(c+2)=c2-1-(c2+3c+2)=-3c-3

4) -2(x-1)x-(x+7)(x2-7x+49)=-2x2+2x-x3-343

5) -(x+2)2-(x-3)(x+4)=-(x2+4x+4)-(x2+4x-3x-12)=-x2-4x-4-x2-x+12=-2x2-5x+8

6) (d+4)3-(d+1)(d+3)=d3+12d2+32d+64-(d2+3d+d+3)=d3+12d2+32d+64-d2-2d-3=d3+10d2+30d+61
