\underline{\textbf{Given:}}

\textsf{Equation is}

\mathsf{2x^2-3x-10=0}

\underline{\textbf{To find:}}

\textsf{Roots of the equation}

\underline{\textbf{Solution:}}

\textsf{We apply quadratic formula to find the roots}}

\mathsf{Here,\;a=2,\;b=-3,\;c=-10}

\underline{\mathsf{Quadratic\;formula:}}

\mathsf{x=\dfrac{-b\pm\,\sqrt{b^2-4ac}}{2a}}

\mathsf{x=\dfrac{3\pm\,\sqrt{(-3)^2-4(2)(-10)}}{2(2)}}

\mathsf{x=\dfrac{3\pm\,\sqrt{9+80}}{4}}

\mathsf{x=\dfrac{3\pm\,\sqrt{89}}{4}}

\therrefore\mathsf{Roots\;are\;\dfrac{3+\sqrt{89}}{4},\;\dfrac{3-\sqrt{89}}{4}}

\underline{\textbf{Find more:}}

( x− 4)( x+ 4) = ( x+ 3)( x− 7) + 35​
