What is the product?(45+2)(5s²+10s+3)O 20s²+20s+6O20s³ +40s² + 12s20s3+10s² +32s+620s3 +50s² +32s+6

Answer 1

Solution

Step 1:

Write the expression

$\left(4s+2\right)\left(5s²+10s+3\right)$

Step 2

Apply the distributive property:

a(m + n) = am + an

Step 3

$\begin{gathered} \left(4s+2\right)\left(5s²+10s+3\right) \\ 4s\left(5s²+10s+3\right)\text{ + 2\lparen5s^^b2+10s+3\rparen} \\ \\ 20s^3\text{ + 40s}^2\text{ + 12s + 10s}^2\text{ + 20s + 6} \\ \\ 20s^3\text{ + 50s}^2\text{ + 32s + 6} \end{gathered}$

Final answer

$20s^3+50s²+32s+6$
