Answer:

0 \:a nd \:  - 2

Step-by-step explanation:

5x^2 +10x

let the roots or zeroes be α,β

thus α+β=-2 (since, α+β=-b/a)

and α-β=2(since,α-β=|√D/a|)

solving simultaneous equations;

thus, α=0 and β= -2

or

factorise the following

5x(x+2)=0

that implies ,

5x=0 or x+2 =0

i.e, x=0,x=-2 are its roots
