The trinomial \( y^2 + 21y + 80 \) can be factored as \( (y + 5)(y + 16) \).
Solución
1. Write the trinomial in descending powers:
\[
y^2 + 21y + 80
\]
2. Look for two numbers whose product is \(80\) and whose sum is \(21\). These numbers are \(5\) and \(16\) because:
\[
5 \times 16 = 80 \quad \text{and} \quad 5 + 16 = 21
\]
3. Factor the trinomial using these numbers:
\[
y^2 + 21y + 80 = (y + 5)(y + 16)
\]

To rewrite the trinomial in descending powers of one variable, we rearrange it as follows: \[ y^2 + 21y + 80. \] Now, to factor the trinomial, we look for two numbers that multiply to 80 and add up to 21. The numbers 16 and 5 fit the bill because \( 16 \times 5 = 80 \) and \( 16 + 5 = 21 \). So, we can factor the trinomial as \[ (y + 16)(y + 5). \]
