Question

FATORE ESTES POLINÔMIOS:

A) 2x³ + 2xy² + x²y + y³=
B) 2a³- 4ab + 5a²b - 10b²=
C) 2x³ + y + 2x² + xy =

Answer 1

A) 2x³ + 2xy² + x²y + y³=

2x(x²+y²) + y(x²+y²)

(2x+y).(x²+y²)

B) 2a³- 4ab + 5a²b - 10b²=

2a(a²-2b) + 5b(a²-2b)

(2a+5b).(a²-2b)

C) 2x³ + y + 2x² + xy =

2x³+2x² + xy+y

2x²(x+1) + y(x+1)

(2x²+y).(x+1)
