Pregunta 32
Step1: Identificar forma canónica
La forma estándar de una ecuación cuadrática es $Ax^2 + Bx + C = 0$.
Step2: Asignar coeficientes
Para $-x^2 + 8x - 4 = 0$:
$A=-1$, $B=8$, $C=-4$
Pregunta 33
Step1: Aplicar raíz cuadrada
Para $x^2=36$, calculamos $\sqrt{x^2}=\pm\sqrt{36}$
Step2: Calcular valores
$\sqrt{36}=6$, así que $x=-6$ y $x=6$
Pregunta 34
Parte 1: Asignar A, B, C
Step1: Usar forma canónica
Usamos $Ax^2 + Bx + C = 0$
Step2: Asignar coeficientes
Para $-x^2 + 2x + 15 = 0$:
$A=-1$, $B=2$, $C=15$
Parte 2: Resolver para $x$
Step1: Multiplicar por -1
$x^2 - 2x - 15 = 0$
Step2: Factorizar la ecuación
$(x-5)(x+3)=0$
Step3: Encontrar valores de $x$
$x-5=0 \implies x=5$; $x+3=0 \implies x=-3$
