solve by completing the square: m^2-1/2m=7/2

Re: solve by completing the square

If you require an instantaneous repsonse, you should consider paying for it. We're just a bunch of volunteers who wander by when we have the time.

Consider this:

(1/2) / 2 = 1/4

(1/4)^2 = 1/16

You are nearly done. Let's see what you get.
 
Re: solve by completing the square

\(\displaystyle A\cdot x^2 \, + B\cdot x \, + \, C = 0\)

\(\displaystyle A\cdot [x^2 \, + \frac{B}{A}\cdot x \, + \, \frac{C}{A}] = 0\)

\(\displaystyle A\cdot [x^2 \, +2\cdot \frac{B}{A}\cdot \frac{1}{2}\cdot x \, + \, \frac{C}{A}] = 0\)

\(\displaystyle A\cdot [x^2 \, +2\cdot \frac{B}{A}\cdot \frac{1}{2}\cdot x \, + \, (\frac{B}{2A})^2 \, - \, (\frac{B}{2A})^2 \, + \, \frac{C}{A}] = 0\)

\(\displaystyle A\cdot [(x \, + \, \frac{B}{2A})^2 \, - \, \frac{B^2 \, - \, 4AC}{4A^2}] = 0\)

and you are done....

If you volunteer some of your time at a soup kitchen,
and a "customer(!)" asks you to be there at a certain time,
what will you answer ?
