Answer 11

So then why isn't it (5x-3)(4x+4) = 5x - 3 * 4x + 4 if you multiply.

Answer 12

you removed the brackets

Answer 13

I'm seeing it as the the distributive property with an invisible 1.

Answer 14

see...(a-b)*(c+d)=ac+ad-bc-cd
get it

Answer 15

No. i'm not that advanced yet.

Answer 16

then you must not say others wrong unless you know it perfectly right

Answer 17

U don't have to be advanced for this...all u have to do is multiply a with c and then a with d after ur done with a u start with b,multiply b with c and then b with d
Got it now?

Answer 18

But when I at my level look at that I see 9x + 1 it's not wrong nor right I only said you were wrong because you said I was wrong. And no Angela I don't get it now.
