Chapter 9: Q.408. (page 982)

Solve using the square root property.
${(4 c - 1)}^{2} = - 18$

Short Answer

Expert verified

The solution is $c = \frac{3 \sqrt{2} i + 1}{4}$ and $c = \frac{- 3 \sqrt{2} i + 1}{4}$ .

Step by step solution

Step 1. Given information.

The given equation is ${(4 c - 1)}^{2} = - 18$ .

Step 2. Apply the square root property.

The property states that if $x = k^{2}$ , then $x = 卤 \sqrt{k}$ .

Step 3. Simplify the equation.

$\begin{array}{rcl} {(4 c - 1)}^{2} & = & - 18 \\ 4 c - 1 & = & 卤 \sqrt{- 18} \\ 4 c - 1 & = & 卤 (\sqrt{18} \sqrt{- 1}) \\ 4 c - 1 & = & 卤 (3 \sqrt{2} i) 鈰� 鈰� 鈰� (i = \sqrt{- 1}) \\ 4 c & = & 卤 3 \sqrt{2} i + 1 \end{array}$

Step 4. Solve the equation for c.

$\begin{array}{rcl} 4 c & = & 3 \sqrt{2} i + 1 \\ c & = & \frac{3 \sqrt{2} i + 1}{4} \end{array}$ and $\begin{array}{rcl} 4 c & = & - 3 \sqrt{2} i + 1 \\ c & = & \frac{- 3 \sqrt{2} i + 1}{4} \end{array}$

Step 5. Simplified answer.

Hence, the required solution is $\begin{array}{rcl} c & = & \frac{3 \sqrt{2} i + 1}{4} \end{array}$ and $\begin{array}{rcl} c & = & \frac{- 3 \sqrt{2} i + 1}{4} \end{array}$ .
