My Favorite No's: Radicals

• They left a radical in the final answer

• They multiplied 4 and 25 when they should have added them

• They multiplied 4 and 25 when they should have multiplied 4 and 5

• They should realize the problem can't be simplified because the radicals aren't the same

• They should add everything first

• They distributed incorrectly

This problem is solved incorrectly. What was the first error this person made?

• There's a distributing error

• They added 50 to both sides when they should have subtracted 50 from both sides

• They added 15 to both sides when they should have subtracted 15

• They divided both sides by 10 when they should have multiplied by 10

• They distributed incorrectly

• They added 15x to both sides instead of subtracting 15x

• They added 50 to both sides instead of subtracting it

• They divided by 10 on both sides instead of multiplying

• They multiplied when they should have added

• They made an arithmetic mistake

• They should not have multiplied nor added because the radicals are not like

• They added 3 to both sides when they should have subtracted it

• They subtracted 5 from both sides when they should have added it

• They added 14 to both sides when they should have subtracted it

• The subtracted 7x from both sides when they have added 7x to both sides

• They squared both sides wrong
