Question
Find the least common denominator for each set of rational expressions. Write each expression in terms of the LCD.$\frac{t+3}{t^{2}-2 t-35} \quad \frac{t-7}{t^{2}+t-20}$
Step 1
We have: \[ \frac{t+3}{t^{2}-2 t-35} = \frac{t+3}{(t-7)(t+5)} \quad \text{and} \quad \frac{t-7}{t^{2}+t-20} = \frac{t-7}{(t-4)(t+5)} \] Show more…
