To factor a difference of squares, the following steps are undertaken: Check if the terms have the greatest common factor (GCF) and factor it out. Remember to include the GCF in your final answer. Determine the numbers that will produce the same results and apply the formula: a2– b2 = (a + b) (a – b) or (a – b) (a + b)
Let me see if I understand your question:
101=50-h
this would just be an equation with a variable: this variable is "h". Variable is an unknown value, like a name for "something".
so we could say that 101 equals 50 minus "something" and we call this something "h"
this is what 101=50-h "means"
as it happens, we can find out the value of this h:
we can subtract 50 from both sides of the equation:
101-50=50-50-h
51=-h
and multiply by (-1)
-51=h
so our h is equal to -51.
so... does not actually mean here 49...
