a)3*(x+y)=3x+3y
b)(3c-5d)*4c-2d=12c²-20dc-2d
c)2*(2ab²-a²b²+a³)=4ab²-2a²b²+2a³
d)2x*(3x-y)+2x+y=6x²-2xy+2x+y
e)3*(x=2z)*4(x²+5x-3)=3x+6z*4x²+20x-12=12x³+60x²-36x+24zx²+120zx-72z
f)a*(a²+b²)-b(a²-b²)=a³+ab²-ba²+b³
g)3*(xy-2xy+x²)=3xy-6xy+3x²=3x²-3xy
h)(2a-6)²*2*(a²-3a)=(4a²--24a+36)*(2a²-6a)=8a⁴- 24a³-48a³+144a²+72a²-216a=8a⁴-72a³+216a²-216a
i)3*(x+3y)=3*x²+6xy+9y²=3x²+18xy+27y²
j)(a+b)²=a²+ab+ab+b²=a²+2ab+b²
