Prosze o obliczenie tego wielomianu: ((3-x+x[potęga2])-(x+2)(x[potega2]-x[potega3]+5))(x-2)

((3-x+x²)-(x+2)(x²-x³+5))(x-2) = ( (3-x+x²) - (x³-x⁴+5x+2x²-2x³+10) ) (x-2) = ( (3-x+x²) - (-x³-x⁴+5x+2x²+10) ) (x-2) = ( 3-x+x²+x³+x⁴-5x-2x²-10) (x-2) = (-7-6x-x²+x³+x⁴) (x-2) = -7x+14-6x²+12x-x³+2x²+x⁴-2x³+x⁵-2x⁴ = 5x+14-4x²-3x³-x⁴+x⁵
