add 3, divide by 3, take the square root, don't forget the \(\pm\)

Add 3 to both sides first
icalibear

what is the aqrt of 243 is it 9 root 3?
icalibear
  • icalibear
sqrt*
xapproachesinfinity
  • xapproachesinfinity
So you get \(3x^2=243\)
misty1212
  • misty1212
divide by 3 next
xapproachesinfinity
  • xapproachesinfinity
Next is to divide by 3
misty1212
  • misty1212
before you take the square root
icalibear
  • icalibear
oh
misty1212
  • misty1212
by some miracle 3 goes in to 243 evenly
icalibear
  • icalibear
so x = 9
misty1212
  • misty1212
don't forget \(-9\)
icalibear
  • icalibear
+- 9
