Solutions

Chapter 1.5, Problem 71E
To determine

Find the real solutions of equation.

Expert Solution

Answer to Problem 71E

  z=34

Explanation of Solution

Given information:

  z232z+916=0

Formula used: -

  x=b±b24ac2a

  z232z+916=0

Now taking L.C.M of 1,2, and 16 to convert the above equation in integer form.

  16z224z+9=0

Now applying quadratic formula:

  x=b±b24ac2a In equation 16z224z+9=0

Here a=16,b=24,c=9

  z=(24)±(24)24(16)(9)2(16)z=24±57657632z=2432z=34
