Answer: The simplified expression is [tex]15x^3+30x[/tex]
Step-by-step explanation:
Since we have given that
[tex]5x(3x^2+6)[/tex]
We need to simplify the expression:
For this we will use "Distributive law":
[tex]a\times (b+c)=a\times b+a\times c[/tex]
[tex]5x(3x^2+6)\\\\=5x\times 3x^2+5x\times6\\\\=15x^3+30x[/tex]
Hence, the simplified expression is [tex]15x^3+30x[/tex]
