f) (x + 1) . (x + 2) =
g) (p + q) . ( 2p – t) =

Answer 1

Explicação passo-a-passo:

5x2. (x3– 2)

5x²*x³-5x²*2

5x⁵-10x²

4x2. (5x – 3)

4x²*5x-4x²*3

20x³-12x²

2m . (3m2– 5m + 7)

2m*3m²-2m*5m+2m*7

6m³-10m²+14m

(2x + 1) . ( x2 + 3x + 1)

2x(x²+3x+1)+1(x²+3x+1)

2x³+6x²+2x+x²+3x+1

2x³+7x²+5x+1

(x + 1) . (x + 2)

x*x+2x+x+2

x²+2x+x+2

x²+3x+2

(p + q) . ( 2p – t)
