A) f(x) = 0 <=> x = -1 or x = 2 or x = 3;
b) x∈(-oo, -1) => f(x) < 0;
x∈(-1, 2) => f(x) > 0;
x∈(2, 3) => f(x) < 0;
x∈(3, +oo) => f(x) > 0;

c
Step-by-step explanation:
Answer:
max = 12
min = 4
heyyy
Step-by-step explanation:
X=numero 1
<span>10-x= numero 2 </span>
<span>x^2 + (10-x)^2 = 58 </span>
<span>x^2 + 100 -20X + x^2 = 58 </span>
<span>2x^2 - 20X + 42 = 0 ....simplificando </span>
<span>x^2 - 10X + 21 = 0...factorizamos </span>
<span>(x-3)(x-7)=0 ...resolvemos las dos partes </span>
<span>x-3=0 -----> x=3 </span>
<span>x-7=0------>x=7 </span>
<span>los dos numeros son 3 y 7 </span>
<span>3^2 + 7^2 = 9+49= 58....Espero te sirva </span>
<span>para el comentario de arriba 36 + 16=52..</span>
