You can put this solution on YOUR website!
At first you must put the last number in the other side of the equation, so we get:
4x^2-48=0, 4x^2=48
Now we divide by 4 in both side of the equations and we get:
4x^/4=48/4, and then we get, x^2=12, now and to finish we have to get the square root of 12.
x=sqrt%2812%29
x=sqrt%284%2A3%29 And now taking out the for of the square root we get
x=2sqrt%283%29 The solution of the equation.
