➥Ur answer :

 \alpha  \: and \:  \beta  \: are \: the \: Zeroes \: of \: the \: Polynomial \: a {x}^{2}  + bx + c = 0 \\ then \:  \alpha  +  \beta  \:  =  \frac{ - b}{ \: a }  \:  \:  \: and  \:  \:  \alpha  \beta  =  \frac{c}{a}  \\  {( \alpha  +  \beta )}^{2}  =  { \alpha }^{2}  +  { \beta }^{2}  + 2 \alpha  \beta  \\   \frac{ {b}^{2} }{ {a}^{2} }  =  { \alpha }^{2} +   { \beta }^{2}  +  \frac{2c}{a}  \\  { \alpha }^{2}  +  { \beta }^{2}  =  \frac{ {b}^{2} }{ {a}^{2} }  -  \frac{2c}{a}  \\  { \alpha }^{2}  +  { \beta }^{2}  =   \frac{ {b}^{2}  - 2ac}{ {a}^{2} }
