a) C(x)=100x+10000 I(x)=15.x² B(x)=15x²-(100x+10000)
B(x)=15x²-100x-10000
B(x)=0
15x²-100x-10000=0
Highlight
a=15
b=-100
c=-10000
x1=29.37
x2=-22.70
Resolvente
I(29.37) = 15.(29,37)² = 12939
I=p.q
12939=p.29,37
12939:29,37=p
440,55=p
B(x)=10000
15x²-100x-10000=10000
15x²-10x-10000-10000=0
15x²-10x-20000=0
a=15
b=-10
