Expert Solution

Answer to Problem 63E

  x=5,x=3

Explanation of Solution

Given information:

  x22x15=0

Formula used: -

  x=b±b24ac2a

  x22x15=0

Now applying quadratic formula:

  x=b±b24ac2a In equation x22x15=0

Here a=1,b=2,c=15

  x=(2)±(2)24(1)(15)2(1)x=2±4+602x=2±642x=2±82

  x=2+82,x=282x=5,x=3
