Answer:
s=-2 s=5
Step-by-step explanation:
https://www.symbolab.com/solver/polynomial-equation-calculator/%20s²%20%2B7s%2B10%3D0%E2%80%8B
ax+b+c=0
s^2+7s+10=0
factor it
2 number na kapag inadd is equal to b at kapag minultiply ay equal sa c
in this case 2 at 5 kasi pag inadd is equal to 7(b) at pag minultiply ay equal to 10( c)
(s+2)(s+5)=0
equate to 0
(s+2)=0;(s+5)=0
transpose / ilipat sa kabilng side ng =sign
if tinraspose the sign will change for example 2 kapag transpose magiging -2.
s=0-2 ; s=0-5
perform the operation
s= -2 ; s= -5
so -2 and -5 are the roots
