How to solve -2p^2=16p+24

Mathematics

frozen [14]3 years ago

Add  2p²  to each side of the equation.  Then you have

                 2p² + 16p + 24  =  0 .

Before you roll up your sleeves and start working on it, you can make it
even more convenient if you divide each side by  2 .  Then you have:

                 p² + 8p + 12 = 0 .

Now you have a nice, comfortable, familiar-looking quadratic equation. 
You can either factor the left side into  (p + 6) (p + 2), or, if you can't find
the factors, you can apply the quadratic formula to it.

That's how to solve it, and find its two solutions.

Which expression can be used to determine 50% of 42?
Crazy boy [7]
Hey there! :D

Since 50% is half of 100%, it would also be half of 42. 

42/2 <== that can be used to determine 50%

42/2= 21

50% of 42 is 21. 

You could also use this:

42*.5= 21 <== this also works

I hope this helps!
