check your typing, is this the way you wanted it to look like ?
Don't try to form fractions
instead place numerator and denominatr within brackets and use / to show the division bar.
e.g. (4x -9)/(x^2+6x-7)
Please help me solve these two equations!!
Divide and express as a polynomial:
12a^8b^5 - 9a^14b^15 + 6a^6b^10
_____________________________________
3a^2b^5
Simplify:
a/b - b/a
__________
a-b/b

4a^6 - 3a^12 b^10 + 2a^4 b^5
(a/b-b/a) / (a-b)/b
= (a^2-b^2)/ab * b/(a-b)
= (a+b)(a-b)/ab * b/(a-b)
= (a+b)/a
(a/b-b/a) / (a-b)/b
= (a^2-b^2)/ab * b/(a-b)
= (a+b)(a-b)/ab * b/(a-b)
= (a+b)/a
