Úprava zlomků v reálných číslech
Uprav v \mathbb{R} a urči podmínky:
\large \Large \frac{{2b}}{{2b+3}}\large -\Large \frac{{4b^{2}+9}}{{4b^{2}-9}}\large -\Large \frac{5}{{2b-3}}\large
=\ – \frac{8}{{2b\ +\ 3}} = \frac{8}{3\ +\ 2b}
\large b \neq \pm \Large \frac{3}{2}\large
=\ – \frac{8}{{2b\ –\ 3}} = \frac{8}{3\ –\ 2b}
\large b \neq \pm \Large \frac{5}{2}\large
=\ – \frac{8}{{2b\ –\ 3}} = \frac{8}{3\ –\ 2b}
\large b \neq \pm \Large \frac{2}{3}\large
=\ – \frac{8}{{2b\ –\ 3}} = \frac{8}{3\ –\ 2b}
\large b \neq \pm \Large \frac{3}{2}\large
