Wykonaj działania na wielomianach. a. (x³+6x²-2x+5)+(2x³-6x²+x-5) b. (4a²-3ab+5b²)+(-a²-3ab-5b²) c.(5x⁴-2x²+6)+(-5x⁴+2x²-6) d.(x³+2x²)-(x²+3x-4) e. 2x³-(4x²-x)+(4x²-x-1) f. 3a³b-(a-5a²b)+(a-8a³b)

a. (x³+6x²-2x+5)+(2x³-6x²+x-5)= =x³+6x²-2x+5+ 2x³-6x²+x-5 = = 3x³-x b. (4a²-3ab+5b²)+(-a²-3ab-5b²)= =4a²-3ab+5b²-a²-3ab-5b²= =3a²-6ab c.(5x⁴-2x²+6)+(-5x⁴+2x²-6)= =5x⁴-2x²+6-5x⁴+2x²-6= =0 d.(x³+2x²)-(x²+3x-4)= =x³+2x²-x²-3x+4= =x³+x²-3x+4 e. 2x³-(4x²-x)+(4x²-x-1)= =2x³-4x²+x+4x²-x-1= =2x³-1 f. 3a³b-(a-5a²b)+(a-8a³b)= =3a³b-a+5a²b+a-8a³b= = -5a³b+5a²b

a. (x³+6x²-2x+5)+(2x³-6x²+x-5)= =x³+6x²-2x+5+2x³-6x²+x-5= =-x+3x³ b. (4a²-3ab+5b²)+(-a²-3ab-5b²)= 4a²-3ab+5b²-a²-3ab-5b²= =-6ab+3a² c.(5x⁴-2x²+6)+(-5x⁴+2x²-6)= =5x⁴-2x²+6-5x⁴+2x²-6= =0 d.(x³+2x²)-(x²+3x-4)= =x³+2x²-x²-3x+4= =x³+x²-3x+4 e. 2x³-(4x²-x)+(4x²-x-1)= =2x³-4x²+4x+4x²-x-1= =2x³+3x-1 f. 3a³b-(a-5a²b)+(a-8a³b)= =3a³b-a+5a²b+a-8a³b= =-5a³b+5a²b życze naj... ;)
