Weba2+2a+1 = (a+1)2 then, according to the law of transitivity, (a+1)2 = 0 We'll refer to this Equation as Eq. #4.2.1 The Square Root Principle says that When two things are equal, their square roots are equal. Note that the square root of (a+1)2 is (a+1)2/2 = (a+1)1 = a+1 Now, applying the Square Root Principle to Eq. #4.2.1 we get: a+1 = √ 0
