Question

find the value of p for which the quadratic equation 4x2+px+3=0 has equal root​

Answer 1

$\huge{\mathcal{\green{\underline{Answer}}}}$

☑ Condition for equal roots :

$b {}^{2} - 4ac = 0 \\ (p) {}^{2} - 4(4)(3) = 0 \\ p {}^{2} - 48 \\ p {}^{2} = 48 \\ p = \sqrt{48}$

Answer 2

Answer:

√48

Step-by-step explanation:

for equal roots it must satisfy

b²-4ac=0. ____(1)

given eqn is 4x²+px+3=0

sub in 1

p²-4(4)(3) =0

p²=48

=> p=√48
