\begin{gathered}:\implies\sf 6x^2 - 3 - 7x \\\\\\:\implies\sf 6x^2 - 7x - 3 = 0 \\\\\\:\implies\sf 6x^2 + 2x - 9x - 3 = 0\\\\\\:\implies\sf 2x(3x + 1) -3(3x + 1)=0\\\\\\:\implies\sf (2x - 3)(3x + 1) = 0\\\\\\:\implies\underline{\boxed{\frak{\pmb{\blue{x = \dfrac{3}{2} \;or\;x = \dfrac{-1}{\;3}}}}}}\;\bigstar\end{gathered}:⟹6x2−3−7x:⟹6x2−7x−3=0:⟹6x2+2x−9x−3=0:⟹2x(3x+1)−3(3x+1)=0:⟹(2x−3)(3x+1)=0:⟹x=23orx=3−1x=23orx=3−1★
\therefore{\underline{\textsf{Hence,\;the\; zeroes\;of\;the\;given\; polynomial\;are\; \textbf{3/2 and -1/3}.}}}∴Hence,thezeroesofthegivenpolynomialare3/2 and -1/3.

☆ If α and β are roots of any Quadratic equation (ax² + bx + c = 0) then Sum and Product is given by :
⠀⠀⠀⠀⋆ Sum (α + β) = (–b)/a
⠀⠀⠀⠀⋆ Product (α β) = c/a
