Solve this quadratic equation 3x(squared)-7=101

3x(squared)-7= 101first we move the 7 across but when we move across an = sign we do the opposite so 101+7now our equation is 3x(squared)=108
now we need to move the 3 across but to do this we need to divide the other side by 3108/3= 36our equation is now x(squared)=36
to get it as x= we need to square root the other side of the equation so sqr root of 36=6sox=6
