As we know the standard form of a quadratic equation is
But when B is equal to 0 in the above it looks like this . However to get the c in the preceding to look like a standard quadratic equation you must add its inverse to the other side.
Take this for example
Obviously you could just do the to get +- 7. But What if you wanted to put it in general quadratic form?
If I wanted to put it general quadratic form would this be correct?
Then just use the multiplicative property of zero to solve both equations and arrive at +- 7?
So in conclusion has my reasoning and calculations been correct up to this point?
