To determine the result of the product of the polynomials, we will use the distributive property:

$(a+b)(c)=ac+bc.$

Using the distributive property, we get:

$(3x+1)(2x^2+x+8)=3x*2x^2+3x*x+3x*8+1*2x^2+1*x+1*8.$

Simplifying the above result, we get:

$6x^3+3x^2+24x+2x^2+x+8.$

Finally, adding like terms we get:

$6x^3+5x^2+25x+8.$

Answer:

$6x^3+5x^2+25x+8.$

Dafna1 [17]

9xa is the common factor.

You can complete the statement by dividing the two terms of the expression of the left side by 9xa, and you will get:

36x^3a + 45xa^2 = 9xa ( 4x^2 + 5a)
