Expert Solution

Answer to Problem 64E

  x=1,x=6

Explanation of Solution

Given information:

  x2+5x6=0

Formula used: -

  x=b±b24ac2a

  x2+5x6=0

Now applying quadratic formula:

  x=b±b24ac2a In equation x2+5x6=0

Here a=1,b=5,c=6

  x=(5)±(5)24(1)(6)2(1)x=5±25+242x=5±492x=5±72

  x=5+72,x=572x=1,x=6
