Si:
A = -8x²y + 3xy – 3y³
B = 4y³ – 7x²y + 2xy
Halla: 2A – 3B
A = -8x²y + 3xy – 3y³
B = 4y³ – 7x²y + 2xy
Halla: 2A – 3B

Explicación paso a paso:
A = -8x²y + 3xy – 3y³
B = 4y³ – 7x²y + 2xy
Halla: 2A – 3B
2(-8x²y + 3xy – 3y³ )-3(4y³ – 7x²y + 2xy)
-16x²y+6xy-6y³-12y³+21x²y-6xy
5x²y-18y³
y(5x²-18y²)
y(5x-18x)(5x+18x)
