Heya!!!
Sin ( x ) + Cos ( x ) = - b / a
Sin ( x ) × Cos ( x ) = c / a
Squaring both sides.
Sin² ( x ) + Cos ² ( x ) + 2 Sin ( x ) Cos ( x ) = - b/a
2 Sin ( x ) Cos ( x ) +1 = - b /a
Put value of Sin ( x ) × Cos ( x ) in above equation
2 ( c / a ) +1 = - b / a
2c + a = - b
squaring both sides
b² = ( 2c + a )²
Have a nice time
