Answer:
[tex](x^{2} + 5)(3x^{2} - 2)[/tex]
Step-by-step explanation:
The polynomial is first correctly stated as follows
[tex]3x^{4} - 2x^{2} + 15x^{2} - 10[/tex]
This is rearranged, grouped and solved as follows:
[tex]3x^{4} + 15x^{2} - 2x^{2} - 10[/tex]
[tex](3x^{4} + 15x^{2}) - (2x^{2} + 10)[/tex]
[tex]3x^{2} (x^{2} + 5) - 2(x^{2} + 5)[/tex]
Factorizing the common factors [tex](x^{2} + 5)[/tex], we have the product of the factored form of the polynomial as follows:
[tex](x^{2} + 5)(3x^{2} - 2)[/tex]
That is the third option in the question if rewritten in the correct form.
