\frac{4y+9}{\left(y-4\right)\left(y+6\right)}+\frac{7}{\left(y-1\right)\left(y+6\right)}
Rastavite y^{2}+2y-24 na faktore. Rastavite y^{2}+5y-6 na faktore.
\frac{\left(4y+9\right)\left(y-1\right)}{\left(y-4\right)\left(y-1\right)\left(y+6\right)}+\frac{7\left(y-4\right)}{\left(y-4\right)\left(y-1\right)\left(y+6\right)}
Da biste zbrojili ili oduzeli izraze, proširite ih da bi imali iste nazivnike. Najmanji zajednički višekratnik brojeva \left(y-4\right)\left(y+6\right) i \left(y-1\right)\left(y+6\right) jest \left(y-4\right)\left(y-1\right)\left(y+6\right). Pomnožite \frac{4y+9}{\left(y-4\right)\left(y+6\right)} i \frac{y-1}{y-1}. Pomnožite \frac{7}{\left(y-1\right)\left(y+6\right)} i \frac{y-4}{y-4}.
\frac{\left(4y+9\right)\left(y-1\right)+7\left(y-4\right)}{\left(y-4\right)\left(y-1\right)\left(y+6\right)}
Budući da \frac{\left(4y+9\right)\left(y-1\right)}{\left(y-4\right)\left(y-1\right)\left(y+6\right)} i \frac{7\left(y-4\right)}{\left(y-4\right)\left(y-1\right)\left(y+6\right)} imaju isti nazivnik, zbrojite ih zbrajanjem njihovih brojnika.
\frac{4y^{2}-4y+9y-9+7y-28}{\left(y-4\right)\left(y-1\right)\left(y+6\right)}
Pomnožite izraz \left(4y+9\right)\left(y-1\right)+7\left(y-4\right).
\frac{4y^{2}+12y-37}{\left(y-4\right)\left(y-1\right)\left(y+6\right)}
Kombinirajte slične izraze u 4y^{2}-4y+9y-9+7y-28.
\frac{4y^{2}+12y-37}{y^{3}+y^{2}-26y+24}
Proširivanje broja \left(y-4\right)\left(y-1\right)\left(y+6\right).
\frac{4y+9}{\left(y-4\right)\left(y+6\right)}+\frac{7}{\left(y-1\right)\left(y+6\right)}
Rastavite y^{2}+2y-24 na faktore. Rastavite y^{2}+5y-6 na faktore.
\frac{\left(4y+9\right)\left(y-1\right)}{\left(y-4\right)\left(y-1\right)\left(y+6\right)}+\frac{7\left(y-4\right)}{\left(y-4\right)\left(y-1\right)\left(y+6\right)}
Da biste zbrojili ili oduzeli izraze, proširite ih da bi imali iste nazivnike. Najmanji zajednički višekratnik brojeva \left(y-4\right)\left(y+6\right) i \left(y-1\right)\left(y+6\right) jest \left(y-4\right)\left(y-1\right)\left(y+6\right). Pomnožite \frac{4y+9}{\left(y-4\right)\left(y+6\right)} i \frac{y-1}{y-1}. Pomnožite \frac{7}{\left(y-1\right)\left(y+6\right)} i \frac{y-4}{y-4}.
\frac{\left(4y+9\right)\left(y-1\right)+7\left(y-4\right)}{\left(y-4\right)\left(y-1\right)\left(y+6\right)}
Budući da \frac{\left(4y+9\right)\left(y-1\right)}{\left(y-4\right)\left(y-1\right)\left(y+6\right)} i \frac{7\left(y-4\right)}{\left(y-4\right)\left(y-1\right)\left(y+6\right)} imaju isti nazivnik, zbrojite ih zbrajanjem njihovih brojnika.
\frac{4y^{2}-4y+9y-9+7y-28}{\left(y-4\right)\left(y-1\right)\left(y+6\right)}
Pomnožite izraz \left(4y+9\right)\left(y-1\right)+7\left(y-4\right).
\frac{4y^{2}+12y-37}{\left(y-4\right)\left(y-1\right)\left(y+6\right)}
Kombinirajte slične izraze u 4y^{2}-4y+9y-9+7y-28.
\frac{4y^{2}+12y-37}{y^{3}+y^{2}-26y+24}
Proširivanje broja \left(y-4\right)\left(y-1\right)\left(y+6\right).
