Given the functions h(x)=2x3−4h\left(x\right)=2x^3-4h(x)=2x3−4 and k(x)=x2+2k\left(x\right)=x^2+2k(x)=x2+2, find and fully simplify h⋅k(x)h\cdot k\left(x\right)h⋅k(x)
h⋅k(x)=2(x5+2x3−2x2−4)h\cdot k\left(x\right)=2\left(x^5+2x^3-2x^2-4\right)h⋅k(x)=2(x5+2x3−2x2−4)
h⋅k(x)=2x5−8h\cdot k\left(x\right)=2x^5-8h⋅k(x)=2x5−8
h⋅k(x)=2x5+4x3−8h\cdot k\left(x\right)=2x^5+4x^3-8h⋅k(x)=2x5+4x3−8
h⋅k(x)=x2+4x+4h\cdot k\left(x\right)=x^2+4x+4h⋅k(x)=x2+4x+4
