Web27 mei 2024 · x2-4x+4 = (x-2)2 then, according to the law of transitivity, (x-2)2 = 5 We'll refer to this Equation as Eq. #2.2.1 The Square Root Principle says that When two things are equal, their square roots are equal. Note that the square root of (x-2)2 is (x-2)2/2 = (x-2)1 = x-2 Now, applying the Square Root Principle to Eq. #2.2.1 we get: x-2 = √ 5 WebProblem: If $ax^2+bx+c=0$ and $2x^2 +3x+4=0$ have a common root where $a,b,c \in \Bbb N$, find least value of $a+b+c$ Solution: Here $2x^2 +3x+4=0$ will give complex roots These roots will be in pair Both equations have a common root $ax^2+bx+c=0$ also have these complex pairs This means least value will be obtained at $a=2$, $b=3$ and $c=4$
