You all know and love the quadratic formula. But what about linear equations? Presenting, the LINEAR FORMULA:
for ax + b = 0
x = -b/a
The simplicity of this method could revolutionalize the teaching of algebra. I am available for media appearances.

If you have ax + b
Then x will simply be
Negative b
Divided by a
If you forget it, that's OK.
If you have ax + b
That's what x will simply be.

You might get some blowback over your choice of a instead of m. Perhaps include both formulas.

Awesome! Do you have one that works when b is less than zero? I run into ax-b=0 all the time and have to do it the long way every time.

You are being sarcastic maybe, but what a great way to untie the quadratic equation! I feel like kids kind of lose what we are solving for

Not to be a critic, but the individual steps of this method had been separately discovered by ancient mathematicians, it’s just the combination of these steps is novel. 😉

It’s amusing that we always care about the y-intercept and never seem to care about the x-intercept .... until we have parabolas.
