HERE WE GO : Let alpha and beta are the 2 roots of the quadratic equation \(\large{ax^2+bx+c=0}\) as per the tutorial that i posted earlier : \[\huge{\alpha = \frac{-b+\sqrt{b^2-4ac}}{2a}}\] \[\huge{\beta=\frac{-b-\sqrt{b^2-4ac}}{2a}}\] 1) Sum of the roots : \[{\alpha + \beta = \frac{-b+\sqrt{b^2-4ac}}{2a}+\frac{-b-\sqrt{b^2-4ac}}{2a}}\] \[\huge{\alpha+\beta=\frac{-2b}{2a}}\] \[\huge{\alpha+\beta=\frac{-b}{a}}\] 2) Product of roots : \[\large{\alpha*\beta=(\frac{-b+\sqrt{b^2-4ac}}{2a})*(\frac{-b-\sqrt{b^2-4ac}}{2a})}\] \[\large{\alpha*\beta=\frac{b^2-b^2+4ac}{4a^2}}\] \[\large{\alpha*\beta=\frac{4ac}{4a^2}}\] \[\huge{\alpha*\beta=\frac{c}{a}}\]
