Chapter 10: Q76. (page 530)

Solve the equation $\frac{15}{p} + p = 16$ . Check your solution.

Short Answer

Expert verified

The solution for the equation is $p = 1, 15$ .

Step by step solution

Step 1. Write down the given equation.

The given equation is $\frac{15}{p} + p = 16$ .

Step 2. Simplify the equation.

The given equation $\frac{15}{p} + p = 16$ is solved as:

$\begin{array}{l} \frac{15}{p} + p = 16.... (Given) \\ 15 + p^{2} = 16 p \\ p^{2} - 16 p + 15 = 0 \\ (p - 15) (p - 1) = 0 \\ p = 1, 15 \end{array}$

Step 3. Verify the result for obtained value.

Plugging $p = 1, 15$ in given equation and verify the result.

$\begin{array}{l} \frac{15}{p} + p = 16.... (Given) \\ \frac{15}{(1)} + (1) = 16.... (For p = 1) \\ 16 = 16.... (Truefor p = 1) \\ \frac{15}{p} + p = 16.... (Given) \\ \frac{15}{(15)} + (15) = 16.... (For p = 15) \\ 16 = 16.... (Truefor p = 15) \end{array}$

Hence the solution is verified for $p = 1, 15$ .

Step 4. Conclusion.

The solution for the given equation is $p = 1, 15$ .
