Question from Dohie, a student:

How do i solve this?

2p^2+4p=16. How do i get p?


Hi Dohie,

I would first add -16 to each side to obtain an equation with the right side being zero. Look for a common factor on the left side and divide both sides by this factor to end up with a quadratic equation in $p$ with the leading term being $p^{2}.$

Now use the technique in my response to Jeff to solve for $p.$
