To determine

To find solution of the equation

Answer to Problem 2.1.2.5P

  $m=\pm 2$

Explanation of Solution

Given information:

Equation is $m^2+1=5$

Calculation:

The given equation is $m^2+1=5$

Solving,

  $m^2=4$

Rooting both sides,

  $\sqrt{m^2}=\pm \sqrt{4}$

So,

  $m=\pm 2$

Hence, value of m is -2, 2
