You can put this solution on YOUR website!
Use the FOIL method to find the product.
You need to multiply the firsts, outers, inners, and lasts.
the firsts are, 2x(x)=2x^2
the outers are, 2x(-10)=-20x
the inners are, 6(x)=6x
the lasts are, 6(-10)=-60
THEN..you need to add like terms.
You can factor this more, but I am not sure if that's what you need to do. You can e-mail me and let me know if you need more help.
