Question

alpha square+beta square in ax square+bx+c

Answer 1

Hi, @ananyakanak
\(\huge \color{red}{\text{Welcome to Open Study}}\ddot\smile\)

you want \(\alpha^2+\beta^2\)
where \(\alpha \) and \(\beta\) are the roots of \(ax^2+bx+c\)
right ?
can you find the sum and product of the roots first ?
then you can use, \(\alpha^2+\beta^2=(\alpha+ \beta )^2-2\alpha \beta\)
