Question
practice finding the solutions of quadratic equations.
what are the values of the coefficients and constant term of $0 = 4 - 7x^2 + x$ in standard form?
$a = \square$
$b = \square$
$c = \square$
Step1: Recall standard quadratic form
La forma estándar de una ecuación cuadrática es $ax^2 + bx + c = 0$, donde $a$, $b$ son los coeficientes y $c$ es el término constante.
Step2: Rearrange given equation
Reordenamos la ecuación dada $0 = 4 - 7x^2 + x$ a la forma estándar:
$$-7x^2 + x + 4 = 0$$
Step3: Identify coefficients/constant
Comparamos con $ax^2 + bx + c = 0$ para encontrar los valores:
- $a$ es el coeficiente de $x^2$: $a = -7$
- $b$ es el coeficiente de $x$: $b = 1$
- $c$ es el término constante: $c = 4$
