Make a the subjects when a^2+ b^2=c^2

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)]

first one is a: renaming a fraction. second one is c: de-c
