Solve by any method:                 3x2 +27x = 30
 
Divide by 3:                                   x2 + 9x = 10
 
Subtract 10 from both sides:      x2 + 9x - 10 = 0
  
Factor:                                            (x + 10) (x - 1) = 0
 
Set each factor = to zero:           x + 10 = 0  and x - 1 = 0
 
Solve:                                              x = -10, 1
 
Note, you can check these answers by plugging them into the original equation.
