Question

Escreva na forma A=X² + BX + C = 0 quando.
A)A=1,b=-6,c=3
b)A=-¹_5;b=0;c=-8
c(A=76;b=0;c=0
d)A=15,b=10,c=0
f)A=15,b=10,c=0
g)A=20,b=10-,c=15

Answer 1

A) 1 = x² + (-6)x + 3 = 0 
B) -1/5 = x² + x + (-8) = 0
C) 76 = x² + x = 0 
D) 15 = x² + 10x = 0 
E*) 15 = x² + 10x = 0 (é igual mesmo?!)
F*) 20 = x² + 10x + 15 = 0
