The answer is $6 x^{4} - 10 x^{2}$ $6x^4 - 10x^2$ .

When multiplying two polynomials, it is necessary to multiply the terms in the first bracket with every term in the second one.

$(2 x) (3 x^{3} - 5 x)$ $(2x)(3x^3 - 5x)$
= $(2 x) (3 x^{3}) + (2 x) (- 5 x)$ $(2x)(3x^3) + (2x)(-5x)$
= $6 x^{4} - 10 x^{2}$ $6x^4 -10x^2$
