Question 127045: The demand and supply equations for a certain item are given by
D = –5p + 40
S = –p^2 + 30p – 8
Find the equilibrium price

-5P+40=-p^2+30p-8
p^2-5p-30p+8+40=0
p^2-35p+48=0
p=(35+-sqrt[-35^2-4*1*48])/2*1
p=(35+-sqt[1225-192])/2
p=(35+-sqrt1033)/2
p=(35+-32.14)/2
p=(35+32.14)/2
p=67.14/2
p=33.57 answer.
p=(35-32.14)/2
p=2.86/2
p=1.43 answer.
