Step by step
Now u want to solve this if give the square root of (12) its=3.46,But u can’t give the square root of (3x) because we don’t know the value of x,So here i want solve it for u by quick and easy way,
Give the ( )^2 for both sides to cancel the square root and find the x value by move the -12 to other side and,It will be 3x=12 and u have to move 3 under the 12 so it will be x=4
And how will u gonna know that ur answer is correct? U have to put for in ur native equation that it will=0 it’s mean that ur answer is correct.
