Answer 1

Answer:

Step-by-step explanation:

$WKT\\\\for \;ax^2+bx+c=0\\\\If\;\;\alpha\;\;and\;\;\beta\;\;are\;\;roots\;\;then\\\\\alpha+ \beta=-\frac{b}{a}\\ \\\alpha\beta=\frac{c}{a}\\\\Now\\\\Given\\\\x^2+4x+2a=0\\\\roots \;\;are\;\;\alpha\;\;and\;\;\frac{2}{\alpha}\\\\Now\\\\\alpha\times\frac{2}{\alpha}=2a\\\\2=2a\\\\a=1$
