Question

Factor completely. If the polynomial is not factorable, write prime.

18.) 3a^2bx + 15cx^2y + 25ad^3y

Answer 1

\[3a^2bx + 15cx^2y + 25ad^3y\]

Answer 2

@ganeshie8 @iGreen @paki

Answer 3

does one of your answers begin with 25?

Answer 4

just read answer my question and DON'T type the question into Goggle cause the problems to the question aren't the same @DivineSolar

Answer 5

I am not firejay :)! I think it is prime because you can only really simplify the problem factoring just changes the equation to, 25ad^3y + 3a^2bx + 15cx^2y

Answer 6

So in all it does not factor leaving it prime.

Answer 7

I say it's prime, because 25 doesn't go into 3 evenly, but 15 does.

Answer 8

Why i agree with that though :).

Answer 9

Considering the fact you can't even factor it. It is prime.

Answer 10

Nope all of them have to factor with the major one and in this case it's 3

Answer 12

Haha using an online calculator to do it :). And that proves my point. It can't be factored ;)

Answer 13

I never said @ganeshie8 OR @DivineSolar that you were wrong, it's the fact that 15 and 25 both don't go into 3 evenly to factor it out

Answer 14

I understand that ^-^! Anyways good luck with the rest of your quiz/test/assignment that you are doing that involves this question.

Answer 15

What I was saying was there was no point in putting it in Wolfram Alpha or ignoring what was saying about the 3, 15, and 25 can't go into each other. *Note multiplying 3 * 25 to get 75 won't work, because the factor tree of 75 doesn't have any number that can be added to equal 15 in the middle.*
