Question

boa gente mim ajude a responder essa questão

Answer 1

x^2 +11x+10=0
resolvendo pela fórmula de Bhaskara
a=1
b=11
c=10
delta=b^2-4ac
delta=(11)^2-4.1.10
delta=121-40
delta=81

x=-b+-raiz delta/2a
x= [-11 +-raiz81]/2a

x'=(-11+9)/2.1
x'=-2/2
x'=-1

x"=(-11-9)/2.1
x"=-20/20
x"=-10

x'= -1 e x"= -10

(m+35)/(n-4)
(-10+35)/(-1-4)
25/-5
-5
