Question 828722: Can you please show me how to break down and solve (x-1)(x-1)-(6x+6)(x+1)
Answer by jim_thompson5910(35256) (Show Source):
You can put this solution on YOUR website! First use the idea that (a+b)(c+d) = a(c+d) + b(c+d)
to go from this
(x-1)(x-1)-(6x+6)(x+1)
to this
x(x-1)-1(x-1)-[6x(x+1)+6(x+1)]
----------------------------------------------------------------
Then distribute to get
x^2-x-x+1-[6x^2+6x+6x+6]
-----------------------------------------------------------------
Afterwards, distribute that negative through to get this
x^2-x-x+1-6x^2-6x-6x-6
-----------------------------------------------------------------
And finally, combine like terms to get this
-5x^2-14x-5
=====================================================================
So the final answer is -5x^2-14x-5
