3x^2 - 4x - 5x^2 + 8x
simplify it

Which expression is equivalent to? assume x > 0 and y > 0.

Hell . what are the solutions to `10x^2 - 38x - 8 = 0`? is this when i find the factors and use the numbers within the factors to determine the zeros? i hope that made sense lol

1. how do you convert the repeating, nonterminating decimal 0. to a fraction? explain the process as you solve the problem.
