1. Answer:

   to find the nature of the roots we need to find the discriminant value

   ∆=b²–4ac

   b²–4ac=(–4)²–4(5)(50)=16–1000=–984

   ∆<0 ,so roots are not real and equal

2. a=5 b=-4 c=50

   therefore, d= b^2 – 4ac

   d= (-4)^2 – 4*5*50

   d= 16 – 1000

   d= – 984

   since, d < 0

   therefore, not real and not equal
