Question

Prosze o pmoc .

1. Dodaj i odejmij wielomiany .

W(x)= 5x³+6x²-8x+12

P(x)= 7x³-11x²+9x-1

W(x) + P(x) W(x) - P(x)

2.Pomnuż wielomiany .

(3x²-8x-2) · (6x-4)

Answer 1

Answer 2

W(x) + P(x)

5x³+6x²-8x+12 + 7x³-11x²+9x-1 = 12x³-5x²+x+11

 

W(x) - P(x)

5x³+6x²-8x+12- (7x³-11x²+9x-1) = 5x³+6x²-8x+12 -7x³+11x²-9x+1 = -2x³+17x²-17x+13

 

 

(3x²-8x-2) · (6x-4) = 18x³ - 12x²-48x²+32x-12x+8 = 18x³ -60x²+20x+8
