please answer this!!!

Answer 1

Answer:

1} given quadratic equation is 5x²-2x-3=0

nature of roots

a=5 b=-2 c=-3

=b²-4ac

=(-2²)-4(5)(-3)

=56

2} given quadratic equation is 2x²-√5x+1

nature of roots

a=2 b=-√5 c=1

=b²-4ac

=(-√5²)-4(2)(1)

=-5-8

=-13

hope it is helpful

Answer 2

Answer:

5x^2-2x-3=0

5x^2-(5x-3x)-3 =0

5x^2-5x+3x-3=0

5x(x-1)+3(x-1)=0

(x-1)(5x+3)=0

x=1 or x=-3/5
