வர்க்கமூலம் (4x^2-9x+2)(7x^2-13x-2)(28x^2-3x-1)

தீர்வு:

= \sqrt{(4 x 2-9 x+2)(7 x 2-13 x-2)(28 x 2-3 x-1)}

= 4 x^{2}-x-8 x+2

= x(4 x-1)-2(4 x-1)

= (x-2)(4 x-1)

7 x^{2}-13 x-2 \\=>7 x^{2}-14 x+x-2

7 x(x-2)+1(x-2)

= (7 x+1)(x-2)

\begin{aligned}=&28 x^{2}-3 x-1\\=&28 x^{2}-7 x+4 x-1\\=&7 x(4 x-1)+1(4 x-1)\\=&(7 x+1)(4 x-1)\end{aligned}

\begin{\sqrt{ (x-2)(4 x-1)(7 x+1)(x-2) (7 x+1)(4 x-1)}}\end{array}

==\sqrt{(x-2)^{2}(7 x+1)^{2}(4 x-1)^{2}}  

வர்க்கமூலம் =  |(x-2)(7 x+1)(4x -1)|
