Question

m^2-25/2m=5/2    solve by completing the square use radicals as needed use commas to separate answers

chaise · Answer

m^2 - 25/2m = 5/2

First of all lets rid of the denominators. Multiply both sides by 2m.

m^2 - 25 = 5m
m^2 -5m - 25 = 0
m^2 - 5m +6.25 -31.25 = 0
(m-(5/2))^2 -31.25 =0

I'm sure you can do the rest. I'm bored.

ive been posting most of my answers to see if they were right i couldnt figure this one out

anonymous · Answer

$$m^2 -25 - 5m = 0$$
$$m^2 -25 -5m +25/4 -25/4 = 0$$
$$(m - 5/2)^2 = 125/4$$
$$m = \frac{5}{2} \pm \sqrt{\frac{125}{4}}$$
