Chapter 4.2, Problem 9CFU

To determine

To solve: The equation $p^2-6p+5=0$

Answer to Problem 9CFU

  $p=1\text{ or }p=5$

Explanation of Solution

Given information: $p^2-6p+5=0$

Calculation:

  $p^2-6p+5=0$ ,

That is:

  ${\left(p-3\right)}^2=-5+9=4,$

Thus: $p-3=\pm 2$

Therefore:

  $x=2+3=5\text{ or }x=-2+3=1$

  $p=1\text{ or }p=5$
