Question

Which is the correct expansion of (3x+2)(3x^2+4)

Answer 1

Answer:6x + 3x^2 +4

depending on what your on

Step-by-step explanation:

Answer 2

Answer:

9x^3 + 6x ^2 + 12x + 8

Step-by-step explanation:

Do each individually.

First (3x^2)(3x) = 9x^3

Then (3x^2)(2) = 6x^2

Then (3x)(4) = 12x

Then (4)(2) = 8

Finally add everything together, since everything has a different exponent, then just combine like I have above.
