so im doing some algebra here and im having a hard time figuring out this stuff, its been awhile since ive done it last. if someone who is really good at math could help me out real fast, that would be nice.
1.(4/4x-1)(16x^2 -1/-15x) simplify it.
2.a^1/4 b^3 -------------- simplify a^-1 b^9/2
3.-4x^2 + 5x - 3=0 solve using the quadratic formula
tell me if there are any questions you have regarding the problems
