Here is a method that makes it seem easier.
<span>Write down any number between 51 and 59. </span>
<span>For example you might choose 57 = 3*19 </span>
<span>Divide both numbers by 10 and write the answer as </span>
<span>0.3 * 1.9 = 0.57</span>
Factor:
(m+5)(m+7)
Solve for the numbers inside, set it = to 0:
m+5=0 >solve
m=-5
m+7=0>solve
m=-7
