What is the following simplified product? assume x> 0 (the > has a line under it)
(sqrt10x^4 -xsqrt5x^2)(2sqrt15x^4 +sqrt3x^3)

a. 10x^4 sqrt6 +x^3 sqrt30x -10x^4 sqrt3 +x^2 sqrt15x

b. 10x^4 sqrt6 +x^3 sqrt30x -x^4 sqrt75 +x^2 sqrt15

c. 10x^4 sqrt6 +x^3 sqrt30x -10x^4 sqrt3 - x^2 sqrt15

d. 10x^4 sqrt6 +x^3 sqrt30x -10x^4 sqrt3 -x^3 sqrt15x
