Question

Escreva a equação ax² + bx + c = 0 para cada conjunto de coeficientes dados.
a) a= 2, b= -3 e c = 0
b) a = 1/3, b = -1 e c = 5

Answer 1

a)

$ax^2 +bx+c = 0 \longrightarrow (2)x^2 + (-3)x +0 = 0 \\\therefore 2x^2-3 = 0$

b)

$ax^2 +bx+c = 0 \longrightarrow \frac{1}{3}x^2 + (-1)x + 5 = 0 \\\therefore \dfrac{1}{3}x^2 -x +5 = 0$

Answer 2

Resposta:

)

\begin{gathered}ax^2 +bx+c = 0 \longrightarrow (2)x^2 + (-3)x +0 = 0 \\\therefore 2x^2-3 = 0\end{gathered}ax2+bx+c=0⟶(2)x2+(−3)x+0=0∴2x2−3=0

b)

\begin{gathered}ax^2 +bx+c = 0 \longrightarrow \frac{1}{3}x^2 + (-1)x + 5 = 0 \\\therefore \dfrac{1}{3}x^2 -x +5 = 0\end{gathered}ax2+bx+c=0⟶31x2+(−1)x+5=0∴31x2−x+5=0
