[tex](mn)(x) = x^3+9x^2+15x+27[/tex]
Step-by-step explanation:
Given
[tex]m(x) = x^2+3\\n(x)= 5x+9[/tex]
We have to find (mn)(x) which means that two functions have to be multiplied to get the end result
[tex](mn)(x) = m(x) +n(x)\\= (x^2+3)(5x+9)\\=x^2(5x+9) + 3(5x+9)\\= x^3+9x^2+15x+27[/tex]
Hence,
[tex](mn)(x) = x^3+9x^2+15x+27[/tex]
