12) Find the value of p for which the quadratic equation 4x2 + px +3 = 0 has equal roots. ​

Answer 1

$\begin{gathered} b {}^{2} - 4ac = 0 \\ (p) {}^{2} - 4(4)(3) = 0 \\ p {}^{2} - 48 \\ p {}^{2} = 48 \\ p = \sqrt{48} \end{gathered}</p><p>☑ Condition for equal roots :</p><p>\huge{\mathcal{\green{\underline{Answer}}}}$
