Answer:

option B is correct option

Answer 2

Answer:

2x square+3x-5=0

Step-by-step explanation:

1)2x square-3x-5=0

2x2+2x-5x-5

2x(x+1)+5(x+1)

2x+5=0,x+1=0

x=-5/2,x=-1

2)2x2+3x-5=0

2x2-2x+5x-5=0

2x(x-1)+5(x-1)

2x+5=0,x-1=0

x=-5/2,x=1

so, 2nd option is correct

I hope this answer may help you
