1 . 2. При а=0,36 b=2 3. надо начертить функцию

Решите задачу:

$\frac{a}{a-3} - \frac{ a^{2}-2a+6 }{ a^{2}-3a } = \frac{a}{a-3} - \frac{ a^{2}-2a+6 }{ a(a-3) }= \frac{ a^{2}- a^{2} +2a-6}{a(a-3)} = \frac{2(a-3)}{a(a-3)} = \frac{2}{a}$

$\frac{ a^{2} +3b}{a} -a= \frac{ a^{2} +3b- a^{2} }{a} = \frac{3b}{a} = \frac{3*2}{0.36} = \frac{6*100}{36} = \frac{100}{6} =16 \frac{4}{6} =16 \frac{2}{3} =16,666$

$y= \frac{ x^{2} -6x+9}{3-x} = -\frac{ (x-3)^{2} }{x-3} =3-x$
