INTRODUCTORY EXERCISES-Symbol Manipulation

(7) Solve the following equations.

 
  
 (a) x(x + 3) = 0 

 (b) 2y = (1/2)y2 

 (c) (x - 2)(3x + 5) = 0

 (d) 3x(2x + 1)(x - 8) = 0

 (e) (x2 - 9x)(x + 4) = 0 
  



HINT: 
 
 For each question, use the "zero-product property":
     if  (a)(b) = 0  then  a = 0  or  b = 0
