Question

X^2+mx+2=0 का एक मूल 1 है तो m का मान क्या होगा​

Answer 1

$\huge{\mathfrak{\green{\star{Answer}}}}$

$x {}^{2} + mx + 2 = 0 \\ ( 1) {}^{2} + (1)m + 2 = 0 \\ 1 + m + 2 = 0 \\ m + 3 = 0$

$\large{\implies{x=-3}}$

Answer 2

Answer:

यदि aX2 + bX + c=0 का मूल एक दूसरे का व्युत्क्रम हो तो इनका मान क्या होगा!

Let the roots be a and it's reciprocal (व्युत्क्रम) 1/a

So, It's product=1

Given Equation:- ax²+bx+c=0{Quardratic Equation)

•°• Product of Roots (मूल)=c/a

According to the Question;

c/a=1

c=a
