3x^2 = 12 |
Hi Shafan,
If you divide both sides of the equation by 3 then the resulting quantities are still equal so you have
3x2 = 12
3x2/3 = 12/3
The threes on the left side cancel and hence
x2 = 4
Do you know a number whose square is 4? Do you know another number whose square is 4?
I hope this helps,
Penny
