I entered a new era of erm...unhappiness when it comes to this...Could someone help with these...
Using the quadratic formula to solve x2 – 4 = 0 and -4x2 + 4x + 80 = 0
This keeps getting harder lol I know how to do the simple ones but when they are switched up like that it gets hard...
Actually it's online, and the lesson has that formula but the answers are a bit different, the one you solved for me was
x = -2 or x = 2 as an anser for my class, I could tell the difference between your anser in mine, though they looked different I think it's the same either way.
