Question

Si
a-b=2; a^2-b^2=30
Calcular: G=a/b

Answer 1

Respuesta:

Explicación paso a paso:

$a^{2} - b^{2} = (a+b)(a-b)\\ \\(a+b)(a-b)= 30\\(a+b)(2)= 30\\a+b = 15\\\\\left \{ {{a+b=15} \atop {a-b=2}} \right.\\ 2a = 17$$a =\frac{17}{2}$   $b =\frac{13}{2\\}$

$\frac{a}{b}= \frac{\frac{17}{2} }{\frac{13}{2} }$

$\frac{a}{b}= 17/13$
