I am doing a crossword puzzle: THe cause of the Panic of 1837 was ? or too many people buying too much land with too little collateral. It starts with an O and has 15 letters?

Algebra
How do you solve 5x^4-12x^3 by factoring? I tried to pull out an x^3, but x^3(5x-12) is hard to break down further into two groups. There's no factors of 5x really other than 5 and 1, and that won't work. Could you demonstrate?

Algebra
(x+4)^2=18. (x+4)(x+4)-18= x^2+8x-2=0. (x )(x )I have no idea how to factor this because no factors of two will add up to 48. Can you offer an explanation and tips on factoring this sort of question?

Algebra
How do you factor -2x^2+x+15=0? I know it should be (2x ) (x ) but I cannot find two other factors which will yield 15 AND x. 5 and 3 doesn't work and neither does 15 and 1. Could you explain what could?
