Question

solve for r. separate multiple answers with a comma. (r + 25)(r + 29) = 0

Explanation:

Step1: Apply zero - product property

If \(ab = 0\), then either \(a = 0\) or \(b = 0\). For the equation \((r + 25)(r + 29)=0\), we set \(r + 25 = 0\) or \(r+29 = 0\).

Step2: Solve for \(r\) in each case

• When \(r + 25=0\), subtract 25 from both sides of the equation: \(r=- 25\).
• When \(r + 29 = 0\), subtract 29 from both sides of the equation: \(r=-29\).

Answer:

\(-25,-29\)
