State the excluded values of the variables:
1. 35yz^2/14y^2z
2. 7a^3b^2/21a^2b + 49ab^3
3. 4x + 8/x^2 + 6x + 8
4. x^2 + x - 2/x^2 - 3x + 2
5. 4x^2 - 6x - 4/2x^2 - 8x + 8

Excluded values means the values the variables in the denominator could have to make the denominator equal zero.

1) = 5z/2y
2) = 7a^3b^2 / 7ab(3a+7b^2)
= b*a^2 / (3a+7b^2)
3) 4(x+2)/ (x+2)(x+4)
= 4/(x+4)
4) (x+2)(x-1) / (x-2)(x-1)
= (x+2)/(x-2)
5) 2(2x+1)(x-2) / 2(x-2)(x-2)
= (2x+1)/(x-2)

5z/2y
7ab(a^2b/ 3a+7b^2)
4 (x+2)/ (x+2)(x+4)= 4/ x+4
(x+2)(x-1)/ (x-2)(x-1)= x+2/ x-2
(2x+2)(2x-4)/ (2x-4)(x-2)= 2x+2/ x-2
