Have a great day!!!

Answer with explanation:

We have to multiply a binomial with Trinomial.

   [tex]\rightarrow(x+2)(2x^2+9 x +8)\\\\=x \times (2 x^2+9x+8)+2\times (2 x^2+9x+8)\\\\=2x^3+9x^2+8 x+4 x^2+18 x+16\\\\ \text{adding like terms}\\\\=2 x^3+13 x^2+26 x+16\\\\ \text{used distributive property of multiplication with respect to addition and law of indices}}\\\\x^a\times x^b=x^{a+b}\\\\a \times (b+c)=a \times b+a \times c[/tex]
