Question

pllzz ans this by factorization method​

Answer 1

Answer:

-30, 90

Step-by-step explanation:

Please note that the 2 after s represents s square. Also, I haven't written 0 of the right hand side

The solution is

s2 - 90s + 30s - 2700

s(s - 90) + 30(s - 90)

(s + 30)(s - 90)

Therefore

s + 30 = 0

s = -30

OR

s - 90 = 0

s = 90
