Solve each equation, if possible. Write irrational numbers in simplest radical form. Describe the strategy you used to get your solution and tell why you chose that strategy.
1. x^2+4=0
2. x^2-6x+1=0



Answer :

Panoyin
x² + 4 = 0
     - 4  - 4
      x² = -4
       x = +2i

x² - 6x + 1 = 0
x = -(-6) +/- √((-6)² - 4(1)(1))
                       2(1)
x = 6 +/- √(36 - 4)
                 2
x = 6 +/- √(32)
             2
x = 6 +/- 2√(2)
             2
x = 3 + √(2)
x = 3 + √(2)    x = 3 - √(2)
