When I do these questions, these are my answers... Could someone please tell me what i am doing wrong..?

__(x-2)(x-2)__
(x-2)(x+3)

__(x-2)__
(x+3)

__((2)-2)__
((2+3)

__0__
5

= 0

**correct** __x__
x

= 0? DNE?

I still don't fully understand the concept with this one..

**if** **, then** **if** **, then** __(x-1)(x^2+2x+1)__
(x-1)

**Wrong, This is the formula** **Try to do it again.**
x^2-2x+1

(1)^2 - 2(1) + 1

1-2+1

= 0

__(x+5)(x-1)__
(x-1)(x-1)

**No No No, Try to factor the denominator again.** __(x+5)__
(x-1)

__((1)+5)__
((1)-1)

__6__
0

= DNE

__(x-2)(x^2+4x+4)__ **Same mistake, The formula is** **Try to do it again.**
12(x-2)

__(x^2+4x+4)__
12

((2)^2 + 4(2) + 4

12

__4+8+4__
12

=4/3
