Question

1) Efetue as multiplicações entre polinômios:

a) (a – 2) . (a + 3)

b) (2x3 + y4) . (x – 2y2)

c) (2x2 + x + 1) . (5x2 – 2)

Answer 1

a) (a – 2) . (a + 3) =

a²+3a-2a-6

a²+a-6

b) (2x³ + y⁴) . (x – 2y²)

2x⁴-4x³y²+xy⁴-2y⁶

c) (2x² + x + 1) . (5x² – 2)

10x⁴-4x²+5x³-2x+5x²-2

10x⁴+5x³+x²-2x-2
