How's this ...
Solve the square root of two x squared minus three x minus ten equal to x where x equals either positive five or negative two.
To solve you sqare both sides giving you the square root of two x squared minus three x minus ten squared equal to x squared.
Which is equal to two x squared minus three x minus ten equals x squared.
Subtract x squared from both sides leaving you with x squared minus three x minus ten equals zero.
You can factor that down to x minus 5 times x plus two. Finally, each factor can then be finshed off as x equals positive five and negative 2.
