1 so far so good with maths, todays work was quite hard however 2 3 had to work on some completing the square 4 5 also found out how to solve some weird quadratics 6 7 if something is like x^6+x^3+2 its still a quadratic 8 to solve it you would say let y = x^3 9 then rewrite the equation as y^2+y+2 10 then solve with the quadratic formula or factorizing 11 and then cube root the ans to give it in terms of x for the final anwser 12 13 you can only do that when all the powers line up with something that can be divided to match a quadratic 14 so x + x^7 + 23 wouldnt work
