Question

Gente ajudaaa pfv
efetue :
a) 2y(y³-1) =
b)x²(x²+x+1)=
c)-2x²y³(5x²-xy+6y²)=
d)(x+1)(x+3)=
e)(3x+2)(3x-4)=
f)(2x+5)(3x-4)=
g)(x+1)(x²-x+1)=
h)(2y+1)(3y²-2y-11)=
i)(x+2y)(x+y-5)=

Answer 1

2Y^4 - 2Y
X^4 + X³ + X² 
-2X^4Y³ + 2X³Y^4 - 12X²Y^5

d )  X² + 3X + X + 3 = X² + 4X + 3 
e)  9X² -12x  + 6x  - 8 = 9x² - 6x - 8
f) 6x² -8x + 15x - 20 = 6x² + 7x - 20
g) x³- x² + x + x² - x + 1 = x³ + 1 
h)6y³ - 4y² - 22y + 3y² - 2y - 11 = 6y³ - y² - 24y - 11
i) x² + xy - 5x + 2y² + 2xy - 10y = x² + 3xy - 5x-10y + 2y²
