Factor completely, the expression
2x^2+6x-20
I did 2(x^2+3x-10)
then it can go down to
2(x+5)(x-2)
Is this correct?
Thanks for checking my work

1. yes,

You can always check your factored answer by simply expanding it. You must get back the original.

2. Thank you
at first I stopped at the 2(x^2+3x-10) but I thought about it and realized it could be factored further.

Can this expression be factored? 4x^2+9 My homework assignment says to factor completely and this is one of the problems but I don't think this expression can be factored. Am I wrong? If so how do I factor it.
