I've been having some problems with these, if someone could help that's be nice.
Perform the indicated operations and simplify.
x^2 - x - 6 x^2 - 3x - 4
x^2 + 4x + 3 * x^2 - 4x + 3
(Note: This was originally a division problem but I flipped the last fraction to make it multiplication as I think your suppose to, that and I didn't know how to type the division sign.)
Find the lowest common denominator:
5a - 15, 10a - 30
Solve the equation.
2 + x - 1 = x^2 - 1
x + 2 x + 3 x^2 + 5x + 6
Perform the indicated operations and simplify.
