\underline{\textbf{Given:}}

\mathsf{9x^2+x+\dfrac{1}{36}}

\underline{\textbf{To find:}}

\textsf{Factors of}\;\mathsf{9x^2+x+\dfrac{1}{36}}

\underline{\textbf{Solution:}}

\mathsf{Consider,}

\mathsf{9x^2+x+\dfrac{1}{36}}

\textsf{This can be written as,}

\mathsf{=(3x)^2+2\,(3x)\left(\dfrac{1}{6}\right)+\left(\dfrac{1}{6}\right)^2}

\textsf{Using the identity,}

\boxed{\bf\,(a+b)^2=a^2+2ab+b^2}

\mathsf{=\left(3x+\dfrac{1}{6}\right)^2}

\mathsf{=\left(3x+\dfrac{1}{6}\right)\,\left(3x+\dfrac{1}{6}\right)}

\implies\boxed{\mathsf{9x^2+x+\dfrac{1}{36}=\left(3x+\dfrac{1}{6}\right)\,\left(3x+\dfrac{1}{6}\right)}}
