So I tried factoring the first little part.... \[x^45x^3+?x^2?x^2+11x^225x+30=0\] \[(x^45x^3+?x^2)+(?x^2+11x^225x+30)=0\] \[x^2(x^25x+?)+([11?]x^225x+30)=0\] We need to play with that ? a little. What can you replace the question mark in the first trinomial to make it factorable? We are looking at \[x^25x+?\]
