Chapter ISG, Problem 8.5.6P

To determine

To solve for w

Answer to Problem 8.5.6P

  $w=-4$ or $w=-7$ are the values.

Explanation of Solution

Given information:

  $x^2-3x=0$

  $x=w+7$

Calculation:

Thegiven solution is $x^2-3x=0$

Solving equation,

  $x(x-3)=0$

For equation to be 0,

  $x-3=0$ Or $x=0$

So,

  $x=0,x=3$ are the zeroes

Also,

  $x=w+7$

Solving for w

  $w=x-7$

Put value of x in the equation

  $w=0-7$ and $w=3-7$

Hence, $w=-4$ or $w=-7$ are the values.
