2x - 3 ( 4x + 7 )
Use distributive property
2x - 12x + 21
Combine like terms
-10x + 21
And that is as far as you can go, since there is no equal sign and no number or variable on the other side of the equal sign :)
Not quite Saseflower.
2x-3 (4x+7)
the minus belongs to the 3 so tis expands to
2x-12x-3*7 = -10x-21
You have to be very careful with those minus signs :)
It was a really good presentation and almost right - Ill give you your points now but you should duck in and fix it up.
