Dekho
Y^2= 4ax hai
Isme y^2 yaani LHS positive hoga for sure
(Real number mein deal kar rahe hai na )
Aur graph hum x > 0 mein bana rahe hai
Toh iska sidha sa matlab hai a> 0 hoga
Tabhi 4ax ek positive quantity aayegi
Jabki y^2= -4ax mein
Iss case mein
Kyuki - laga diya
Graph y axis ke about mirror image bana kar aa jayega
Dekho isbar x< 0 hai
Toh -4ax phir se positive quantity bana dega 👍
