Divide: PLEASE DONT GUESS AND THE AWNSER IS SUPPOSED TO HAVE X'S IN IT AND PARENTHESES
andre [41]
So remember how you can factor out ones
like (4/8)=(4/4)(1/2)=(1)(1/2)
so first factor each think see if we can simplify any of them
\frac{ \frac{(x+1)(x+1)}{(x-2)} }{ \frac{(x+1)(x-1)}{(x+2)(x-2)} }
can't
ok so remember division of fractions

(a/b)/(c/d)=(a/b)(d/c)=(ad)/(bc)
invert and multiply
so
\frac{ \frac{(x+1)(x+1)}{(x-2)} }{ \frac{(x+1)(x-1)}{(x+2)(x-2)} }=
(\frac{(x+1)(x+1)}{(x-2)}) ( \frac{(x+2)(x-2)}{(x+1)(x-1)}})=
\frac{(x+1)(x+1)(x+2)(x-2)}{(x-2)(x+1)(x-1)}=
( \frac{(x+1)(x+2)}{(x-1)} )( \frac{(x+1)(x-2)}{(x+1)(x-2)} )=
( \frac{(x+1)(x+2)}{(x-1)} )( 1)=
\frac{(x+1)(x+2)}{(x-1)}=
\frac{x^2+3x+2}{x-1}

87/1000 into a decimal is 0.087,
You can divide with your calculator, or you can use place value.
0.8 = 8/10
0.87 = 87/100
0.087 = 87/1000
And so on and so forth...
