I'ma teach you how to solve an equation quadratically.Keep
up if you don't wanna fall behind cause if
you don't follow me it'll be a catastrophe
for you.The quadratic formula spells out -b
+/- square root b squared minus 4ac all over
2a.Plug in the numbers from the quadratic
equation.Let's take 1x squared + 2x + 5 for
example.Now you have negative 2 plus or minus
square root of 2 squared minus 4 times 1 times
5.This is divided by 2 times 1.As you can
see here.If you got negative 1 plus or minus
2i.You got it right.Congrats.I applaud you.Now
you can solve quadratic equations properly
and easily.
