Ok, I need help now with my Algebra test! Please help, and explain work

#10) 6x squared/ 6x squared + 9x + 3 times 6x+3/2x


#17) x+2/x-2 = x-1


#18) 1-1/x squared over 1-1/x
 
Like, do you have to solve for x, simplify, or something crazy?
 
for the first one, is it [6x^2] over [6x^2 + 9x + 3]?
or [6x^2/6x^2] + [9x + 3]?
 
On 10 I have to multiply and simplify

On 17 I have to solve

On 18 I have to simplify

for the first one, is it [6x^2] over [6x^2 + 9x + 3]?
or [6x^2/6x^2] + [9x + 3]?

he doesn't just want the answer, he wants the work too... silly!

Nope. Your solution is wrong.

(x-1)(x-2) = x²-3x+2, not x²-x-2. ;)

Or in other words, you mixed up numerator and denominator in your very initial equation, at least compared with the opening post.

oh damn. i copied the equation wrong.
there we go :)
