Question

Obtenha os coeficientes das equaçoes do 2° grau.
A) 5x² - 7x - 3 = 0
B) X² - 4x + 2 = 0
C) X² - X - 1 = 0
D) 2x² + 7x + 8 = 0

Answer 1

a) $5x^2-7x-3=0$

$a=5~~~~~~~~~~b=-7~~~~~~~~~~c=-3$

b) $x^2-4x+2=0$

$a=1~~~~~~~~~~b=-4~~~~~~~~~~c=2$

c) $x^2-x-1=0$

$a=1~~~~~~~~~~~b=-1~~~~~~~~~~c=-1$

d) $2x^2+7x+8=0$

$a=2~~~~~~~~~~b=7~~~~~~~~~~c=8$
