Question 727294
Can you factor the quadratic expression?  If not or you do not wish to try, then pick either of general solution to quadratic equation or completing the square.  General solution to quadratic equation is often easiest for solving for the variable.  Completing the square is best when you want to know about the graph.


Work using the least advanced thinking.  You'll find that the polynomial is factorable.  FACTOR IT!  SOLVE FROM THAT.
