1.a) F(x)=4*(-3x^3+4x^2+2x-1)=-12x^3+16x^2+8x-4 2.a) x^7*x^5-x^7*x^2-x^6*x^5+x^6*x^2)=x^12-x^9-x^11+x^6 3. a) (3x^2*3x^2+3x^2*4=4x*3x^2-4x*4)=9x^4+12x^2-12x^3-16x=9x^4-12x^3+12x^2-16x b) (3x^2)^3-3[(3x^2)^2*1]+3[(3x^2)*1^2]-1^3=27x^6-27x^4+9x^2-1 c) (5x^5)^3+3(5x^5)^2*3x+3(5x^5)*(2x)^2+(2x)^3=125x^15+225x^11+60x^7+8x^3
2.a) x^7*x^5-x^7*x^2-x^6*x^5+x^6*x^2)=x^12-x^9-x^11+x^6
3. a) (3x^2*3x^2+3x^2*4=4x*3x^2-4x*4)=9x^4+12x^2-12x^3-16x=9x^4-12x^3+12x^2-16x
b) (3x^2)^3-3[(3x^2)^2*1]+3[(3x^2)*1^2]-1^3=27x^6-27x^4+9x^2-1
c) (5x^5)^3+3(5x^5)^2*3x+3(5x^5)*(2x)^2+(2x)^3=125x^15+225x^11+60x^7+8x^3
