4x\left(4x^{2}-12x+9\right)\left(5-x\right)^{3}
Use binomial theorem \left(a-b\right)^{2}=a^{2}-2ab+b^{2} to expand \left(2x-3\right)^{2}.
4x\left(4x^{2}-12x+9\right)\left(125-75x+15x^{2}-x^{3}\right)
Use binomial theorem \left(a-b\right)^{3}=a^{3}-3a^{2}b+3ab^{2}-b^{3} to expand \left(5-x\right)^{3}.
\left(16x^{3}-48x^{2}+36x\right)\left(125-75x+15x^{2}-x^{3}\right)
Use the distributive property to multiply 4x by 4x^{2}-12x+9.
6140x^{3}-1956x^{4}+288x^{5}-16x^{6}-8700x^{2}+4500x
Use the distributive property to multiply 16x^{3}-48x^{2}+36x by 125-75x+15x^{2}-x^{3} and combine like terms.
