Simplify x/6x-x^2
A. 1/6-x; where x = 0,6**
B. 1/6-x where x= 6
C. 1/6x where x=0
D. 1/6
Simplify 5x^3/7x^3+x^4
A. 5/7+x; where x = 0,-7
B. 5/7+x; where x=-7**
C. 5/7x; where x = 0
D. 5/7
brackets are essential here
don't you want to say x ≠ instead of x = ???
A
1/(6-x) , x ≠ 0,6
2nd one:
5(7+x) , x ≠0,-7 ----> choice A
