start with your equation and add 125 to both sides of the = sign
anonymous
  • anonymous
Ok
anonymous
  • anonymous
125 = 80p^2... now divide both sides by 80.. so you'll end up with 125/80. this is p^2. can you reduce the fraction?

Still having trouble understanding, but Continue

125/80 = p^2 . reducing the fraction on the left side, you'll end up with 25/16. so your equation is now 25/16 = p^2
anonymous
  • anonymous
Ok
anonymous
  • anonymous
wait then you square it, right?
anonymous
  • anonymous
So it will be +-5/4 right?
anonymous
  • anonymous
no, take the square root of 25/16
anonymous
  • anonymous
ok, that's what you meant. be careful of the terms because squaring means something totally different from square root"ing"
