a = √[ (c - b) (c + b) ]
Step-by-step explanation:
a^2 + b^2 = c^2
We can make "a" the subject by doing the following:
a^2 + b^2 = c^2
Subtract b^2 from both side:
a^2 = c^2 - b^2
Take the square root of both side
a = √ (c^2 - b^2)
Since we have difference of two squares, we can simplify further as:
a = √[ (c - b) (c + b) ]
